Concise and practical syntheses of (2S)-R207910 (3a) and (2R)-R207910 (3b) have been achieved in high overall yield of 12 % in 10 steps for each isomer starting from a known intermediate following Sharpless asymmetric epoxidation, regioselective epoxide opening, modified allylzinc bromide addition as key reactions.
(2S)-R207910 (3a) 和 (2R)-R207910 (3b) 在 Sharpless 不对称环氧化、区域选择性环氧化物之后,从已知中间体开始,每个异构体分 10 步以 12% 的高总产率实现了简洁实用的合成打开,改性烯丙基溴化锌加成作为关键反应。
