Lipas PS-30 (Amano) was found to be an effective catalyst for enantioselective transesterification of a number of racemic γ and δ hydroxysulfones with isopropenyl acetate in ether. The intramolecularacylation of the ethyl carbonate derivatives obtained from the chiral hydroxysulfones 1d and 1b has been used for the preparation of R(+)-4-hexanolide, sex pheromone of the female dermestid beetle Trogoderma
