A method of an enantioselective nucleophilic addition reaction to
carbonyl, which enables an asymmetric synthesis of an optically active
.alpha.-hydroxy-.gamma.-keto acid ester, an optically active
.alpha.-hydroxy-.gamma.-amino acid ester, hydroxydiketone compounds, etc.
being useful as a raw material or synthesis intermediate for producing a
pharmaceutical preparation, an agricultural chemical, a fragrance, a
functional polymer or the like. In this method, the nucleophilic addition
reaction of enamide compound accompanied by hydroxyl (--OH) formation to
carbonyl is carried out in the presence of a chiral catalyst with copper
or nickel.
