A highly efficient regio- and enantioselective monohydrogenation of 1,4-dienes has been realized using an iridium catalyst with a chiral N,P-ligand under mild conditions. The substrate scope was studied and included both unfunctionalized as well as functionalized substituents on the meta- or para-position. Substrates having substituents with functionalities such as silyl protected alcohols or ketals
使用带有手性 N,P-配体的铱催化剂在温和条件下实现了 1,4-二烯的高效区域选择性和对映选择性单氢化。研究了底物范围并包括间位或对位上的未官能化和官能化取代基。具有取代基的底物如甲硅烷基保护的醇或缩酮以高区域选择性和高对映体过量(高达 98% ee)单氢化。
