Herein, we report an efficient synthetic strategy for an Fe(ii)-catalyzed site-selective ring opening of bicyclo[n.1.0]alkanols and their concomitant 1,6-conjugate addition to p-quinone methides. Access to tertiary carbon centers with appendaged carbocycles of distinct sizes and functional groups are achieved, under a substrate-controlled bond scission of the fused cyclopropanols.

在此,我们报告了一种有效的合成策略,用于 Fe(ii) 催化的双环[n.1.0]烷醇的位点选择性开环及其伴随的 1,6-共轭加成到对醌甲基化物。在稠合环丙醇的底物控制的键断裂下,实现了与具有不同尺寸和官能团的附加碳环的叔碳中心的接触。合成衍生化进一步增强了该方案的实用性。
