(+)- and (-)-5,5-Dimethyl-4-hydroxy-2-cyclopentenone 1 were efficiently synthesized by the dissymmetrization of meso diol 2 with lipase-catalyzed acetylation as a key step. The synthesis of (+)-5,5-dimethyl-4-hydroxy-2-cyclopentenone was also carried out by the chemical conversion of (-)-pantolactone 6.
