ABSTRACT:
A method for producing an optically active alcohol compound comprising reacting a cyclic ether compound with a phenol compound in the presence of an asymmetric complex obtained by reacting an optically active metal complex represented by the formula (1):wherein R1, R2, R3, R4, R5, R6, R7and R8are the same or different and each independently represent a hydrogen atom, an alkyl group or the like;one of R9and R10is a hydrogen group and the other is a substituted or unsubstituted phenyl group or the like;Q represents a single bond, a C1-C4 alkylene group or the like;M represents a metal ion; and when an ionic valency of the metal ion is same as a coordination number of a ligand, A is nonexistent, and when the above-mentioned ionic valency is different from the coordination number, and A represents a counter ion or a ligand, with a zirconium alkoxide or a hafnium alkoxide.
