Gold(I)‐catalyzed cycloisomerization of ortho‐(propargyloxy)arenemethylenecyclopropanes afforded two different types of products, that is, products of methylenecyclopropane migration and cycloisomerization products of the methylenecyclopropane moiety, controlled jointly by electronic and steric effects of the adjacent substituents. Furthermore, the corresponding cycloisomerization products could be
金(I)催化的邻-(炔丙基氧基)亚芳基亚甲基环丙烷的环异构化提供了两种不同类型的产物,即亚甲基环丙烷迁移的产物和亚甲基环丙烷部分的环异构化产物,受相邻取代基的电子和空间效应共同控制。此外,相应的环异构化产物也可以以对映异构体富集的方式产生。
