through asymmetric reduction of ketones or kinetic resolution of secondary alcohols, enantioselective synthesis of the corresponding secondary alcohols is challenging when the two groups attached to the prochiral or chiral centers are spatially or electronically similar. For examples, dialkyl (sp3 vs. sp3), diaryl (sp2 vs. sp2), and aryl-alkenyl (sp2 vs. sp2) alcohols are difficult to produce with high enantioselectivities
无论是通过酮的不对称还原还是仲醇的动力学拆分,当连接到前手性或手性中心的两个基团在空间或电子上相似时,相应仲醇的对映选择性合成都是具有挑战性的。例如,二烷基(sp 3对sp 3)、二芳基(sp 2对sp 2)和芳基烯基(sp 2对sp 2) 醇很难以高对映选择性生产。通过利用我们最近开发的具有最小立体异构性的 Ru 催化剂,我们在本文中报道了通过氢转移对芳基烯醇进行高效动力学拆分。这种方法使用于有机合成的这种通用手性结构单元如烯丙醇能够在实际有用的转化率下以优异的对映体过量轻松获得。
