The first enantioselective total synthesis of enokipodins A–D, highly oxidized α-cuparenone-type sesquiterpenoids with antimicrobialactivity, was accomplished by using Meyers' diastereoselective alkylation protocol for the construction of the C7-quaternary asymmetric center. The present synthesis also constitutes a formal enantioselectivesynthesis of (S)-1,4-cuparenediol and (S)-cuparene-1,4-quinone

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
