摘要：

The synthesis of enantiomerically pure beta, gamma-disubstituted gamma-lactones is described based on the lipase-catalysed asymmetrisation of the cis-cyclopent-2-ene-1,4-diol derivatives 1 or 3. The cyclopentanones 7 and ent-7 have been obtained via epoxidation of the chiral monoacetates 2 or ent-2, respectively, followed by protecting group interconversion and oxidation. Baeyer-Villiger oxidation of 7 and ent-7 and subsequent acidic methanolysis furnished the title compounds 9 and ent-9, respectively.
