Abstract

PURPOSE:To selectively produce a long-chain omega-hydroxyfatty acid ester which is an intermediate for a macrocyclic lactone useful as a raw material for perfumery, in high yield, by reducing a dibasic acid diester with diborane. CONSTITUTION:The objective omega-hydroxyfatty acid ester of formula II (e.g. 12-hydroxydodecanoic acid methyl ester) can be produced by reducing a dibasic acid diester of formula I (R is lower alkyl; n is 10-16) (e.g. dodecanoic diacid dimethyl ester) with diborane. Preferably the diester is used in excess to diborane and the reaction is terminated before the conversion of diester reaches 60%. The unreacted diester can be easily separated and recovered after the reaction and the recovered diester is preferably reused to improve the efficiency.
