first enantioselective total synthesis of enokipodins A, B, C and D, highly oxidized alpha-cuparenone-type sesquiterpenoids possessing antimicrobialactivity, was accomplished in 8-28% overall yields from methyl (2,5-dimethoxy-4-methylphenyl)acetate by applying Meyers' diastereoselective alkylation protocol for the construction of their C7-quaternary asymmetric center. The present synthesis confirmed
