promotion effect of the azolyl group itself, an efficient Co-catalyzed asymmetric hydrogenation of azolyl-substituted alkenes has been successfully developed for the convenient introduction of chirality near the azole ring. It was the first utilization of an azole as the directing group in Co-catalyzed asymmetric hydrogenation. Chiral azoles were obtained in high yields and with excellent enantioselectivities
通过唑基本身的辅助促进作用,成功地开发了一种高效的共催化唑基取代烯烃的不对称氢化,方便在唑环附近引入手性。这是在共催化不对称氢化中首次使用唑类作为导向基团。在温和条件下以高产率和优异的对映选择性获得手性唑类,克级实验在高达 2000 个底物/催化剂的情况下顺利进行。
