为制备式Ib化合物
R1-R11-A1-R5 Ib
将组份R1-R11OH、氨基酸H-A1-OH和胺H-R5互相结合。视需要可将R1-R11OH的羧酸首先与适当保护形式的H-A1-OH偶联,接着断开保护基,与胺H-R5缩合,或者将该适当保护的氨基酸H-A1-OH可先与H-R5反应,该产物在脱保护后与R1-R11OH偶联。
胺的H-R5碱性形式可使用已知方法获得:
其中t=1及u=0,R6、Y及Z如前述,利用如A.L.戴维斯(Davis)等人,J.Med.Chem.18,752(1975)或H.,默兹(Merz),DE 38 23 576(C.A.114(21),207 052m)所述的已知方法制备。在通式XI化合物中引入R6基团是通过与NaH及BrR6反应而进行的。该反应可在外环N上保护基(Sch)的存在或不存在下发生。
此制备方法可由下列示意图表示:
适当的保护基(Sch)是碱稳定的保护基如Boc-基。
为了制备通式XI化合物,通式X化合物在还原条件下环化(例如,类似于A.L.戴维斯(Davis)等人所描述的用铂-黑的方法(J.Med.Chem.2,826(1966))。
按照J.Med.Chem.2,828(1966)中所述,X化合物可从相应取代的1-硝基苄基醇(VII)经由中间阶段VIII及IX(通过卤化作用,如用SOCl2)来制备,接着与乙酰氨基丙二酸二乙基酯反应。
(其中t=1及u=0,R6、Y及Z如前述对式IIa所述说明),可利用例如LiAlH4还原相应的化合物IIa来制备。
制备式IIa化合物(其中t=u=0,R6、Y及Z如前述定义),用A.L.戴维斯(Davis)等人,J.Med.Chem.16,1043(1973)的方法是合适的。此处,从α-溴-O-硝基苯基醋酸甲基酯开始,引入苯二甲酰亚氨基,断开保护基及还原硝基后,发生环化作用形成(取代或未经取代的)3-氨基-2-吲哚酮;
引入R6并还原形成通式IIb的类似化合物,此过程如上述。
引入R6并还原形成类似化合物IIb的过程如上所述。
当使用这种制备方法时,相应取代的2-(2-硝基苯基)-乙基溴(XVIII)可与乙酰氨基丙二酸二乙基酯反应形成化合物XIX,然后形成XX,类似于前述方法。
化合物XX还原形成化合物XXI的作用可在压力下于MeOH及水的溶液中进行,例如,在铂-黑存在下用氢还原。制备化合物XXII的环化作用是用多磷酸同时在搅拌及加热下进行。
化合物IIa(t=u=1,R6、Y及Z如上述定义)的制备可如下进行:将未取代或取代的邻苯二甲酰苯基丙氨酸与胺H2N-R6偶合,然后用甲醛在Pictect-Spengler类反应中环化。最后,该邻苯二甲酰基例如通过用羟基胺处理而断开:
形成式IIb的类似化合物的还原反应可按上述所示方法进行。
(其中R6、Y及Z如上述定义)的制备是按G-来勒克(G-Leclerc)等人,J.Med.Chem.29,2427(1986)中所述方法进行。为此目的,将取代或未取代的3-溴喹啉首先转化成相应的N-氧化物,然后转化成喹啉-2-酮,最后将胺基在压力下(在载体管中)与氨一起引入:
取代基R6的引入可按如前所述有关化合物IIa的方式进行。
(其中R6如上述定义,R8代表羟基,R9是氢)可按R.卫屈特(Weichert),Arkiv Kemi 25,231(1966)中的方法进行。此处,乙醯氨基丙二酸单乙基酯与取代或未取代的2-硝基苯甲醛反应,然后水解,还原硝基,最后进行环化作用:
R6的引入如上述进行。
为制备化合物IVa(其中R9代表(C1-5)烷氧基,苯基-(C1-5)烷氧基,萘基-(C1-5)烷氧基或(C1-4)烷基羰基或其中R8及R9一起代表氧基或-OCH2CH2O-),上述化合物IVa(其中R6代表氢及R6代表羟基)可进行如下反应:
(a)制备R9是烷氧基、苯基或萘基烷氧基的化合物IVa:按威廉森法(Williamson)进行醚化反应;
(b)制备R9是烷氧基羰基的化合物IVa:与相应的酸酐反应;
(c)制备R8及R9一起代表氧的化合物IVa:按例如欧本勒(Oppenauer)氧化;
(d)制备R8及R9皆代表-OCH2CH2O-的化合物IVa:将(c)所得的酮基化合物与乙二醇反应。
为制备通式H-R5的胺(其中R7是烷基),将通式IIa、IIb、IIIa及IVa化合物烷基化。此烷基化反应可通过先保护外环N(例如用三氟乙酰基)再进行烷基化(例如用烷基溴),然后断开保护基(例如通过水解)。
