An efficient and stereoselective synthesis of the C1‐C9 moiety of the 7,8‐O‐isopropylidene protected iriomoteolide 3a derivative has been accomplished. In our strategy, we employed olefin cross‐metathesis of the L‐(+)‐tartaric acid derivative (((4S,5S)‐2,2‐dimethyl‐5‐vinyl‐1,3‐dioxolan‐4‐yl)methoxy)(tert‐butyl)diphenylsilane with a synthesized methyl (S)‐3‐methylhex‐5‐enate to successfully provide
已完成7,8 - O-异亚丙基保护的iriomoteolide 3a衍生物的C1-C9部分的高效立体选择性合成。在我们的策略中,我们使用了L -(+)-酒石酸衍生物(((4 S,5 S)-2,2-二甲基-5-乙烯基-1,3-二氧戊环-4-基)(甲氧基)(叔丁基)二苯基硅烷与合成的(S)-3-甲基己基-5-烯酸甲酯成功地提供所需片段的正确烯烃几何形状。
