Owing to the biological significance and great synthetic value of 1,4-diarylbutane-1,4-diols and their derivatives, increasingly considerable attention has been paid to developing effective synthetic methods for chiral 1,4-diarylbutane-1,4-diols. We herein report an efficient asymmetric hydrogenation of 1,4-diaryldiketones catalyzed by a chiral iridium complex bearing -amphox as ligand, furnishing a series of 1,4-diarylbutane-1,4-diols in excellent yields (up to >99%) with exceptional enantioselectivities (up to >99.9% ee) and diastereoselectivities (up to >100 : 1 dr).
由于 1,4-二芳基丁烷-1,4-二醇及其衍生物具有重要的生物学意义和巨大的合成价值,因此人们越来越关注开发手性 1,4-二芳基丁烷-1,4-二醇的有效合成方法。本文报道了一种手性铱配合物催化的 1,4-二芳基二酮的不对称氢化反应,以 -amphox 为配体,该反应提供了一系列具有优异收率(高达>99%)、对映选择性(高达>99.9%ee)和非对映选择性(高达>100:1 dr)的 1,4-二芳基丁烷-1,4-二醇。
