METHOD FOR PREVENTING LOWERING OF OPTICAL PURITY |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To inhibit lowering of optical purity of a reduction reaction product caused by a transition metal complex used as a catalyst. <P>SOLUTION: The manufacturing method of a reduction reaction product comprises adding a nitrogen-containing compound to a reaction liquid obtained by a reduction reaction where a transition metal complex is used and subsequently recovering and/or distilling a reaction solvent. <P>COPYRIGHT: (C)2012,JPO&INPIT |
