Asymmetric hydrogenation of diaryl 1,4-diketones was achieved by using trans-RuCl2[(S)-BINAP)][(S)-Daipen] as the catalyst and the reaction gave rise to excellent enantio- and diastereoselectivities (up to >99% ee and de). This procedure provides a convenient and efficient synthetic method for chiral 1,4-diarylbutane-1,4-diols, which are important intermediates for a variety of chiral auxiliaries and
使用反式-RuCl 2 [( S )-BINAP)][( S )-Daipen] 作为催化剂实现了二芳基 1,4-二酮的不对称氢化,反应产生了优异的对映选择性和非对映选择性(高达 > 99% ee和de )。该方法为手性 1,4-二芳基丁烷-1,4-二醇提供了一种方便有效的合成方法,该方法是多种手性助剂和配体的重要中间体。
