An efficient rhodium‐catalyzed asymmetric hydrogenation of challenging tetrasubstituted cyclic enamides has been developed, affording cyclic chiral amides with high yields and excellent enantioselectivities (up to 99% yield and >99% ee). This novel methodology provides an efficient and concise synthetic route to chiral cycloalkylamines with two contiguous stereogenic centers. The potential utility
已经开发出有效的铑催化具有挑战性的四取代环烯酰胺的不对称氢化反应,可提供高收率和出色的对映选择性(高达99%收率和> 99%ee)的环状手性酰胺。这种新颖的方法为具有两个连续的立体异构中心的手性环烷基胺提供了一种高效,简洁的合成途径。还公开了该方案在生物活性分子合成中的潜在效用。
