The first enantioselective total synthesis of enokipodins A–D, highly oxidized α-cuparenone-type sesquiterpenoids with antimicrobial activity, was accomplished by using Meyers' diastereoselective alkylation protocol for the construction of the C7-quaternary asymmetric center. The present synthesis also constitutes a formal enantioselective synthesis of (S)-1,4-cuparenediol and (S)-cuparene-1,4-quinone
利用Meyers的非对映选择性烷基化方案构建C7季不对称中心,完成了首个对映体全合成的烯基鬼臼草碱A–D,高度氧化的具有抗微生物活性的α-cuparenone型倍半萜。本合成也构成(正式对映选择性合成小号)-1,4- cuparenediol和(小号)-cuparene-1,4-醌。
