摘要 本文以苯基乙基甲酮为还原底物,研究了原地(in situ)制备的在3、4、5位具有不同取代基的手性1,3,2-(口恶)唑硼烷催化剂的结构与不对称催化效应关系。研究结果表明,在不对称催化硼烷还原反应中(CBS方法),产物的构型和对映选择性主要受手性(口恶)唑硼烷的4位取代基控制。 An effect of substituent of chiral 1, 3, 2 - oxazaborolidine on enantioselectivity was studied by employing propiophenone as reducing substrate. The results indicated that the configuration and enantioselectivity of product were mainly controlled by the substituent at the carbon 4 of oxazaborolidine in CBS reduction.
