The present invention provides a method for producing a reduction reaction product, wherein recovery of the reaction solvent and/or distillation is carried out after adding a nitrogen-containing compound into a reaction liquid of a reduction reaction that has been conducted using a transition metal complex. The present invention is capable of suppressing decrease in the optical purity of the reduction reaction product due to the transition metal complex used as a catalyst.
本发明提供了一种生产还原反应产物的方法,其中在使用过渡
金属络合物进行还原反应的反应液中加入
含氮化合物后,进行反应溶剂回收和/或蒸馏。本发明能够抑制由于过渡
金属络合物用作
催化剂而导致的还原反应产物光学纯度的降低。
