InI(3) and InBr(3) have been found to be effective catalysts for the π activation of C≡C bonds to initiate the conversion of chiral propargylic alcohols or silyl ethers to polycyclic products in excellent yields and with high stereoselectivity. The method has been applied to the synthesis of chiral fused hexacyclic ring systems with the creation of multiple new stereocenters. The power and scope of
已发现 InI(3) 和 InBr(3) 是 C≡C 键的 π 活化的有效催化剂,以引发手性炔丙醇或甲硅烷基醚以优异的产率和高立体选择性转化为多环产物。该方法已应用于手性稠合六环系统的合成,并产生多个新的立体中心。该方法的威力和范围通过各种示例进行了说明。
