Highly enantioselective pyridine-directed rhodium-catalyzed asymmetric hydrogenation of challenging 1,1-diarylalkenes is achieved by using [Rh(NBD)DuanPhos]BF4 as a precatalyst. Various types of 2-pyridine substituted 1,1-diarylalkenes could be hydrogenated with good to excellent enantioselectivities, which provide an efficient route to the synthesis of pharmaceutically and biologically active compounds
通过使用[Rh(NBD)DuanPhos] BF 4作为预催化剂,可以实现对映选择性1,1-二芳基烯烃的高度对映体吡啶定向的铑催化的不对称氢化。各种类型的2-吡啶取代的1,1-二芳基烯烃可以良好的至优异的对映选择性进行氢化,这为合成包含2-吡啶基乙烷单元的药物和生物活性化合物提供了一条有效途径。
