Abstract

PURPOSE:To readily and advantageously obtain the titled compound useful as an intermediate for producing higher perfume ingredient or medicine in high yield, by cyclizing omega-hydroxy fatty acid ester used as a starting substance in the presence of an acid. CONSTITUTION:The aimed compound such as 1,15-pentadecanolide is obtained by cyclizing omega-hydroxy fatty acid ester expressed by the formula (R is lower alkyl; n is 8-17) such as 15-hydroxypentadecanoic acid methyl ester, readily obtained at a low cost by converting a long-chain diacid monoester into an acid halide and then catalytically reducing the acid halide, preferably in a solvent such as p-xylene or toluene in the presence of catalytic amount of acid - excess acid, e.g. organic sulfonic acid such as p-toluene sulfonic acid or methane sulfonic acid at 50-200 deg.C, preferably 100-170 deg.C.
