METHOD FOR PREVENTING DECREASE IN OPTICAL PURITY |
摘要 |
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. |
