()-(-)-Mevalonolactone was synthesized starting from a chiral tertiary α-benzyloxy ester, obtained by the lipase-catalyzed enantioselective hydrolysis of the corresponding racemate, in 7 steps and 21.5% overall yield. Intramolecular Friedel-Crafts reaction of an intermediate worked well as the key-step for the new carbon-carbon bond formation.
