Abstract

Abstract An improved procedure of esterification of propynoic acid, based on the N, N′- dicyclohexylcarbodiimide 4-dimethylaminopyridine condensation, is presented, which gives good results with primary, secondary, allylic and homoallylic alcohols. Reactions conditions are mild. Some limitations are given.
