Abstract

NEW MATERIAL:An aldehyde compound of formula I (R1 is 1W6C alkyl, group of formula II, etc.; R2 is alkyl, alkenyl, alkynyl, etc.; R3 is H, alkyl, alkenyl, phenyl, etc.).
EXAMPLE: 3-Acetyl-2-methyl-3-p-toluenesulfonyl-hex-5-yn-1-al.
USE: Useful as a synthetic intermediate for cyclopentenolone which is a synthetic intermediate for allethrin useful as an agricultural chemical, and an intermediate for prostaglandin useful as a medicine.
PROCESS: An acetal compound of formula III (R7 is 1W3C alkyl) is reacted with an acid, e.g. hydrochloric acid, in the presence of water at a temperature in the range of -60W60°C for 5minW3hr to give the compound of formula I.
