| 1. A method of an enantioselective nucleophilic addition reaction of enamide, which is a method of a nucleophilic addition reaction of an enamide compound accompanied by generation of a hydroxyl group (—OH) to a carbonyl group, being characterized by allowing the reaction to be performed in the presence of a chiral catalyst comprising copper or nickel. |
