    Abstract: The present invention relates to a method of producing an optically active cyanohydrin derivative, which comprises reacting an aldehyde or an asymmetrical ketone with a cyanating agent in the presence of a Lewis base and a titanium compound produced from a partial hydrolysate of titanium tetraalkoxide and an optically active ligand represented by formula (II) or a titanium oxoalkoxide compound represented by formula (I) [TixOy](OR1)4x-2y, and an optically active ligand represented by formula (II), wherein R1 is an optionally substituted alkyl group or an optionally substituted aryl group; x is an integer of not less than 2; y is an integer of not less than 1; and y/x satisfies 0.1
