Provided is a process for producing an optically active hydroxyaldehyde or aminohydroxyaldehyde. The process for producing an optically active hydroxyaldehyde or aminohydroxyaldehyde is characterized by reacting an aldehyde or an imine with a boric acid enol ester in the presence of a copper compound and an optically active bidentate phosphine compound.
