An efficient synthesis of carbo- and heterocycles using CC, CO and CN bonds under cobalt catalysis is described. The substituents on olefins are key for controlling the regio- and chemoselectivity in the initial hydrogen atom transfer step and quaternary carbons are efficiently constructed under mild conditions. Cyclopropane cleavage and tandem cyclization give highly functionalized bicyclic skeletons
描述了在钴催化下利用C C,C O和C N键有效合成碳环和杂环的方法。烯烃上的取代基是控制初始氢原子转移步骤中区域和化学选择性的关键,并且在温和条件下可以有效地构建季碳。环丙烷裂解和串联环化可在一次操作中得到高度官能化的双环骨架。
