amphidinolide B1 have been accomplished. The 1,3-isomerization of allylic alcohol 10 was accomplished via rhenium oxo catalysis and has been applied successfully in the synthesis. (-)-MIB-catalyzed asymmetric vinylzinc addition to aldehyde 31 and the regio- and stereoselective epoxidation of unsymmetrical divinyl methanol 32 were key steps.

tandem ring-closingmetathesis of a silaketal-based dienyne substrate proceeded efficiently to provide a bicyclic siloxane, which upon removal of the silicon tether afforded an (E,Z)-1,3-dienediol. Further manipulation of this key functional motif rendered synthesis of the entire C1−C19 linear skeleton of (−)-cochleamycin A, a late-stage intermediate employed in the previous totalsynthesis of (+)-cochleamycin
基于硅缩醛的二炔底物的串联闭环复分解有效地进行以提供双环硅氧烷,其在去除硅系链后提供( E , Z) -1,3-二烯二醇。对该关键功能基序的进一步操作使得 (-)-cochleamycin A 的整个 C1-C19 线性骨架合成,这是 Roush 及其同事先前在 (+)-cochleamycin A 全合成中使用的后期中间体。
