The gold(I)- or Brønsted acid-catalyzed reaction of unactivated vinylcyclopropanes (VCPs) with sulfonamides affords useful homoallylic amine derivatives. This ring-opening reaction occurs in a highly selective manner affording in the case of α-phenyl-substituted VCPs products with the E-configuration exclusively.
未活化的乙烯基环丙烷(VCP)与磺酰胺的金(I)或布朗斯台德酸催化反应可提供有用的均烯丙基胺衍生物。该开环反应以高度选择性的方式发生,在α-苯基取代的VCPs产物仅具有E-构型的情况下提供。
