Progress toward the totalsynthesis of hederacines A and B is described. Our approach involves an allylic cyanate-to-isocyanate rearrangement, eneyne ring-closing metathesis, and a transannular reaction between the C-5 amino group and the C-12 position of the perhydroazuleno[5,6-b]furanone intermediate.
描述了向全合成二十碳五烯A和B的进展。我们的方法涉及烯丙基氰酸酯到异氰酸酯的重排,烯键闭环复分解以及C-5氨基和过氢azuleno [5,6- b ]呋喃酮中间体的C-12位置之间的跨环反应。
