A novel stereoselective total synthesis of ophiocerin C was accomplished starting from l-(+)-tartaric acid. The C3,C4 vic-diol moiety was obtained from tartaric acid, and the stereogenic centre at C6 was created by substrate-controlled epoxidation and subsequent regioselective cleavage of the epoxide ring. Wittig reactions - tartaric acid - epoxidations - ring opening - ophiocerin C - stereoselective
从1 -(+)-酒石酸开始,完成了新的立体选择性的ophiocerin C合成。C3,C4 vic -diol部分是从酒石酸获得的,C6的立体异构中心是通过底物控制的环氧化作用和随后环氧化物环的区域选择性裂解而形成的。 Wittig反应-酒石酸-环氧化-开环-ophcercerin C-立体选择性合成
