  enantioselective borohydride reduction of aromatic ketones or imines to the corresponding alcohols was developed in the presence of a catalytic amount of an optically active cobalt(II) complex catalyst. This enantioselective reduction is carried out using a precisely premodified borohydride with alcohols such as tetrahydrofurfuryl alcohol, ethanol and methanol. High optical yields are obtained by choosing

  在催化量的光学活性钴（II）络合物催化剂的存在下，芳香族酮或亚胺对映体的高度对映选择性硼氢化物还原。该对映选择性还原是使用精确预改性的硼氢化物与醇（例如四氢糠醇，乙醇和甲醇）进行的。通过选择合适的醇作为改性剂和合适的催化剂β-酮亚氨基配体，可以获得高的光学收率。对映选择性硼氢化物还原已成功应用于光学活性的1,3-二醇的制备，双酰基二茂铁的立体选择性还原以及1,3-二羰基化合物的动态和/或动力学拆分。
