A straightforward methodology for the synthesis of anti‐Markovnikov‐type alcohols is presented. By using a specific cobalt triphos complex in the presence of Zn(OTf)2 as an additive, the hydrogenation of epoxides proceeds with high yields and selectivities. The described protocol shows a broad substrate scope, including multi‐substituted internal and terminal epoxides, as well as a good functional‐group
提出了一种简单的合成抗马尔可夫尼可夫醇的方法。通过在Zn(OTf)2作为添加剂的情况下使用特定的钴三光配合物,可以高收率和选择性地进行环氧化物的氢化。所描述的方案显示了广泛的底物范围,包括多取代的内部和末端环氧化物,以及良好的官能团耐受性。各种天然产物衍生物,包括类固醇,萜类和倍半萜类,都以中等至优异的产率获得了相应的醇。
