Description
Til tross for den omfattende bruk og anerkjennelse av penicilliner og cefalosporiner, beta-laktam antibiotika, når det gjelder å bekjempe bakterie-infeksjoner, er det visse medlemmer av gruppen som ikke er aktive overfor resistente mikroorganismer på grunn av organismenes evne til å produsere et beta-laktamase-enzym som reagerer med beta-laktam antibiotika og lager produkter som ikke har antibakteriell virkning. Imidlertid har visse stoffer evnen til å undertrykke beta-laktamaser, og kan, når de brukes sammen med et penicillin eller cefalosporin, øke eller forsterke den antibakterielle virkningen av antibiotikumet mot visse beta-laktamase-produserende mikroorganismer. Despite the widespread use and recognition of penicillins and cephalosporins, beta-lactam antibiotics, when it comes to fighting bacterial infections, there are certain members of the group that are not active against resistant microorganisms due to the organisms' ability to produce a beta -lactamase enzyme that reacts with beta-lactam antibiotics and creates products that have no antibacterial effect. However, certain substances have the ability to suppress beta-lactamases and, when used with a penicillin or cephalosporin, can increase or enhance the antibacterial action of the antibiotic against certain beta-lactamase-producing microorganisms.
Vest-tysk off.skrift nr. 2.824.535 publisert 14. desember 1978, angir at pencillansyresulfon er en slik effektiv beta-laktamase-inhibitor. Videre blir det forklart i nevnte skrift at visse estere av pencillansyresulfon hydrolyseres lett in vivo og gir høyt blodnivå av denne beta-laktamase-inhibitoren. Videre, U.K. patentsøknad 2.044.255 og belgisk patent 883.299 angir også at halogenmetyl-estere av pencillansyresulfon kan være nyttige mellomprodukter i syntesen av lett hydrolyserbare estere som omdannes in vivo til penicillansyresulfon og et beta-laktam-antibiotikum. West German Official Publication No. 2,824,535 published December 14, 1978, states that pencillanic acid sulfone is one such effective beta-lactamase inhibitor. Furthermore, it is explained in the aforementioned publication that certain esters of pencillanic acid sulfone are easily hydrolyzed in vivo and give high blood levels of this beta-lactamase inhibitor. Furthermore, the U.K. patent application 2,044,255 and Belgian patent 883,299 also indicate that halomethyl esters of penicillanic acid sulfone can be useful intermediates in the synthesis of readily hydrolyzable esters which are converted in vivo to penicillanic acid sulfone and a beta-lactam antibiotic.
I denne siste henvisning, omfatter den anbefalte måte for In this last reference, it includes the recommended way of
å fremstille den egnede halogenmetyl-ester av pencillansyresulfon, at et salt av den nevnte syre reagerer med et dihalogen-metan. Selv om den er gjennomførbar, fører denne fremgangsmåte til uønskede biprodukter som skyldes reaksjonen mellom to mol av syren med ett mol av dihalogenmetanet, eller alternativt betraktet, en videre reaksjon av halogenmetyl-esteren med et annet mol av pencillansyresulfon-saltet. to prepare the suitable halomethyl ester of pencillanic acid sulfone, that a salt of said acid reacts with a dihalomethane. Although feasible, this process leads to undesirable byproducts resulting from the reaction of two moles of the acid with one mole of the dihalomethane, or alternatively, a further reaction of the halomethyl ester with another mole of the pencillanic acid sulfone salt.
Den foreliggende oppfinnelse gjelder et mellomprodukt for The present invention relates to an intermediate product for
å syntetisere halogenmetyl-estere av penicillansyresulfon som unngår den ovenfor nevnte dannelse av biprodukter. to synthesize halomethyl esters of penicillanic acid sulfone which avoid the above-mentioned formation of by-products.
Klormetyl-estere av enkle syrer har blitt fremstilt ved Chloromethyl esters of simple acids have been prepared by
at det korresponderende syreklorid har reagert med formaldehyd i nærvær av sinkklorid (J. Am. Chem. Soc., 43, 660 (1921), og likeledes ved at en fri syre har reagert med formaldehyd og saltsyre i nærvær av sinkklorid (Chem. Abst. 53, 4119 fg (1959)). that the corresponding acid chloride has reacted with formaldehyde in the presence of zinc chloride (J. Am. Chem. Soc., 43, 660 (1921), and likewise by a free acid having reacted with formaldehyde and hydrochloric acid in the presence of zinc chloride (Chem. Abst 53, 4119 fg (1959)).

Mellomproduktene ifølge oppfinnelsen kan anvendes for å fremstille en forbindelse med formel , The intermediate products according to the invention can be used to prepare a compound with the formula,
der X er klor, brom eller jod, og R er hydrogen eller metyl. where X is chlorine, bromine or iodine, and R is hydrogen or methyl.
Forbindelsen ifølge oppfinnelsen har formelen The compound according to the invention has the formula
der R er hydrogen eller metyl, Rx er alkyl med fra ett til seks karbonatomer eller fenyl, og n er 0 eller 1. Forbindelsen med formel II omsettes med en halogenoverfører i et reaksjonsinert oppløsningsmiddel, for å danne en forbindelse med formel I. where R is hydrogen or methyl, Rx is alkyl of from one to six carbon atoms or phenyl, and n is 0 or 1. The compound of formula II is reacted with a halogen transfer agent in a reaction-inert solvent to form a compound of formula I.
Fremstillingen av forbindelsene med formel I er nærmere beskrevet i stamsøknaden 81.4226. The production of the compounds of formula I is described in more detail in parent application 81.4226.
En foretrukket gruppe forbindelser, er de hvor R^. er det nevnte alkyl og n er 0. Spesielt foretrukket er de forbindelser der R er hydrogen og R^ er metyl, og der R er hydrogen og Rx er t-butyl. A preferred group of compounds are those where R^. is the aforementioned alkyl and n is 0. Particularly preferred are those compounds where R is hydrogen and R 1 is methyl, and where R is hydrogen and R x is t-butyl.
En annen foretrukket gruppe forbindelser er de hvor R^ er fenyl og n er 0. Særlig foretrukket er den hvor R er hydrogen. Another preferred group of compounds are those where R 1 is phenyl and n is 0. Particularly preferred is the one where R is hydrogen.
En tredje foretrukket gruppe forbindelser er de hvor R^ er nevnte alkyl og n er 1. Særlig foretrukket er den hvor Rx er metyl og R er hydrogen. A third preferred group of compounds are those where Rx is said alkyl and n is 1. Particularly preferred is that where Rx is methyl and R is hydrogen.
Forbindelsene med formel II ifølge foreliggende oppfinnelse kan fremstilles ved at et basesalt, fortrinnsvis natriumsaltet, får reagere med et halogenmetylsulfid. The compounds of formula II according to the present invention can be prepared by allowing a base salt, preferably the sodium salt, to react with a halogen methyl sulphide.
I praksis blir ett mol av et basesalt av penicillanatsulfon og ett mol av halogenmetylsulfid blandet i et reaksjonsinert oppløsningsmiddei i nærvær av en katalytisk mengde, vanligvis en ti-del av et mol, av et tetraalkylammoniumhalogenid, så som tetrabutylammoniumbromid eller -jodid. Katalysatoren inkluderes for å aktivere dannelsen av det ønskede produkt. I tillegg til det ovenfor, tilsettes også et mol natriumbikarbonat til reaksjonsblandingen. In practice, one mole of a base salt of penicillanate sulfone and one mole of halomethyl sulfide are mixed in a reaction-initiated solvent in the presence of a catalytic amount, usually one-tenth of a mole, of a tetraalkylammonium halide, such as tetrabutylammonium bromide or iodide. The catalyst is included to activate the formation of the desired product. In addition to the above, one mole of sodium bicarbonate is also added to the reaction mixture.
Kriteriene for et reaksjonsinert oppløsningsmiddei for reaksjonen som fører til de tidligere nevnte mellomprodukter, er tilsvarende de for den patentkrevde fremgangsmåten i den foreliggende oppfinnelse. De nevnte oppløsningsmidler burde løse opp reaktantene uten å reagere i nevneverdig grad med hverken reaktantene eller produktet under reaksjonsbetingelsene. Det er også å foretrekke at de nevnte oppløsningsmidler har koke- og fryse-punkt som lar seg forene med reaksjonstemperaturen. Det foretrukne oppløsningsmiddei for den nevnte reaksjon er aceton, selv om en rekke andre oppløsningsmidler som er blandbare med vann, inkludert dimetylformamid og heksametylfosforamid også kan brukes. The criteria for a reaction-initiated solvent for the reaction leading to the previously mentioned intermediates are similar to those for the patent-claimed method in the present invention. The mentioned solvents should dissolve the reactants without reacting to an appreciable extent with either the reactants or the product under the reaction conditions. It is also preferable that the mentioned solvents have boiling and freezing points which can be reconciled with the reaction temperature. The preferred solvent for the aforementioned reaction is acetone, although a number of other water-miscible solvents, including dimethylformamide and hexamethylphosphoramide, may also be used.
Reaksjonstiden avhenger av konsentrasjonen, reaksjons-temperatur og startreagensenes reaktivitet. Når reaksjonen utføres ved den foretrukne temperatur på omkring 50-75°c, er reaksjonen vanligvis i alt vesentlig fullstendig på 3-4 timer. Av bekvemmelighetshensyn får reaksjonen ofte foregå over natten, uten noen skadelig virkning på produktet. The reaction time depends on the concentration, reaction temperature and the reactivity of the starting reagents. When the reaction is carried out at the preferred temperature of about 50-75°C, the reaction is usually substantially complete in 3-4 hours. For convenience, the reaction is often allowed to take place overnight, without any detrimental effect on the product.
Når reaksjonen er fullstendig, kan oppløsningsmidlet, hvis det har et relativt lavt kokepunkt, fjernes i vakuum, og residuet fordeles mellom vann og et oppløsningsmiddei som ikke er blandbart med vann, så som metylenklorid. Når det organiske oppløsningsmidlet fjernes, fremkommer produktet, fritt fra alle vannoppløselige materialer. Hvis reaksjons-oppløsningsmidlet er et høytkokende oppløsningsmiddei som er blandbart med vann, kan reaksjonsblandingen helles raskt i vann, og produktet ekstraheres, som bemerket ovenfor, med et oppløsningsmiddei som ikke er blandbart med vann, så som metylenklorid. When the reaction is complete, the solvent, if it has a relatively low boiling point, can be removed in vacuo and the residue partitioned between water and a water-immiscible solvent such as methylene chloride. When the organic solvent is removed, the product appears, free of all water-soluble materials. If the reaction solvent is a high-boiling water-miscible solvent, the reaction mixture can be poured rapidly into water and the product extracted, as noted above, with a water-immiscible solvent such as methylene chloride.
Fremstilling av disse forbindelsene med formel II, hvor n er 1, utføres hensiktsmessig ved oksydering av de forbindelsene hvor n er 0, og omfatter at ett mol av sulfidet (n=0) får reagere med én ekvivalent av et oksydasjonsmiddel i et reaksjonsinert oppløsningsmiddei. Preparation of these compounds of formula II, where n is 1, is conveniently carried out by oxidizing the compounds where n is 0, and comprises that one mole of the sulfide (n=0) is allowed to react with one equivalent of an oxidizing agent in a reaction-initiated solvent.
Selv omi et bredt spekter av oksydasjonsmidler kan brukes når det gjelder å overføre sulfidet til et sulfoksyd, er det foretrukne middel m-klorperbenzoesyre. For å minske påvirkningen mellom oppløsningsmidlet og oksydasjonsmidlet, er det å foretrekke at et halogenert hydrokarbon-oppløsningsmiddel, så som metylenklorid, brukes. Although a wide range of oxidizing agents can be used in converting the sulfide to a sulfoxide, the preferred agent is m-chloroperbenzoic acid. In order to reduce the interaction between the solvent and the oxidizing agent, it is preferable that a halogenated hydrocarbon solvent, such as methylene chloride, is used.
Reaksjonstemperaturen er ikke kritisk, og reagensene blandes til å begynne med ved -20 til 0°C, og får varmes til værelsestemperatur. Ved omgivelsenes temperatur er reaksjonen vanligvis fullstendig på omkring 45-60 minutter. The reaction temperature is not critical, and the reagents are initially mixed at -20 to 0°C and allowed to warm to room temperature. At ambient temperature, the reaction is usually complete in about 45-60 minutes.
De sure biproduktene ved reaksjonen fjernes ved at den organiske fase vaskes med bikarbonat, og produktet isoleres ved at det organiske lag konsentreres. The acidic by-products of the reaction are removed by washing the organic phase with bicarbonate, and the product is isolated by concentrating the organic layer.
