A synthetic method that relies on Au(I)-catalyzed tandem 1,3-acyloxy migration/double cyclopropanation of 1-ene-4,9-diyne and 1-ene-4,10-diyne esters to construct the respective architecturally challenging tetracyclodecene and tetracycloundecene derivatives is described. Achieved under mild reaction conditions, the transformation was shown to be robust with a wide variety of substitution patterns tolerated
一种基于Au(I)催化的1-ene-4,9-diyne和1-ene-4,10-diyne酯的串联1,3-酰氧基迁移/双环丙烷化的合成方法,以构建各自在结构上具有挑战性的四环癸烯描述了四环十一碳烯衍生物。该反应在温和的反应条件下完成,显示出强大的转化能力,可耐受多种取代模式,从而使碳环家族的两个成员均具有良好至极佳的收率,并具有单一的区域和非对映异构体。
