A method of an enantioselective nucleophilic addition reaction to carbonyl, which enables an asymmetric synthesis of an optically active α-hydroxy-γ-keto acid ester, an optically active α-hydroxy-γ-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.
本方法是一种手性催化剂铜或镍存在下的烯酰胺化合物伴随着羟基(-OH)形成的亲核加成反应到羰基中,使得产生具有光学活性的α-羟基-γ-酮酸酯、α-羟基-γ-氨基酸酯、羟基二酮化合物等,这些化合物可作为制备制药、农业化学品、香料、功能性聚合物等原料或合成中间体。
