Title:
METHOD FOR PRODUCING ENANTIOMERS, METHOD FOR IMPROVING ENANTIOSELECTIVITY, METHOD FOR CONTROLLING SYNTHESIS OF ENANTIOMER SPECIES, AGENT FOR IMPROVING ENANTIOSELECTIVITY, ENANTIOSELECTIVITY-VARIABLE MATERIAL, ENANTIOSELECTION CONTROLLING MATERIAL, ASYMMETRIC SYNTHESIS REACTION DEVICE, COMPLEX, AND METHOD FOR SEPARATELY PRODUCING R-ISOMER AND S-ISOMER
Document Type and Number:
WIPO Patent Application WO/2017/051856
Kind Code:
A1
Abstract:
A method for producing a specific enantiomer in a larger amount than the other enantiomer, said method comprising reacting a reaction substrate in the presence of cellulose nanofiber or a derivative thereof and a catalyst so as to improve the yield. The present invention makes it possible to improve the yield and enantioselectivity in an asymmetric synthesis reaction.
