摘要/Abstract

手性醇及手性胺化合物被广泛应用于有机合成、材料科学、医药、农用化学及精细化工，酮及亚胺的不对称硼氢化反应为制备该类化合物提供了有效手段.频哪醇硼烷，自1991年被报道以来，作为一种稳定的、商品化的、易定量的有机硼试剂被广泛应用于羰基化合物、亚胺及腈类化合物的还原反应及其机理研究中.在过去5年里，频哪醇硼烷也被应用于不对称硼氢化反应，以制备手性醇及手性胺.按不同的催化剂，如地球丰产过渡金属、主族元素及稀土金属分类，介绍频哪醇硼烷参与的酮和亚胺的不对称催化硼氢化反应.

Enantioselective hydroboration of ketones and imines provides a powerful method to access valuable chiral alcohols and amines which are widely used in organic synthesis, materials science, pharmaceutical, agrochemistry and fine chemical industry. After invented in 1991, pinacolborane (HBpin) as a stable, commercially available and measurably simple reductive reagent has been widely applied in hydroboration of carbonyl derivatives, imines and nitriles and relevant mechanistic investigation. In the past 5 years, HBpin has also been employed for asymmetric catalytic hydroboration (CHB) to access chiral alcohols and amines. The enantioselective CHB reactions of ketones and imines using HBpin are outlined according to the classification of different catalysts, such as earth abundant transition metals, main group elements, and rare-earth metals.
Key words: pinacolborane, asymmetric hydroboration, earth abundant transition metal, ketone, imine
