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, R7 and R8 are the same or different and each independently represent a hydrogen atom, an alkyl group or the like;
one of R9 and R10 is 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.
一种生产光学活性醇化合物的方法,包括在由式(1)表示的光学活性金属络合物反应得到的不对称络合物存在下,使环醚化合物与苯酚化合物反应:
其中 R1、R2、R3、R4、R5、R6、R7 和 R8 相同或不同,且各自独立地代表氢原子、烷基或类似基团;
R9 和 R10 中的一个是氢基,另一个是取代或未取代的苯基或类似基团;
Q 代表单键、C1-C4 亚烷基或类似物;
M 代表金属离子;当金属离子的离子价与配体的配位数相同时,A 不存在,当上述离子价与配位数不同时,A 代表金属离子。
当上述离子价与配位数不同,且 A 代表反离子或配体时,用氧化锆或氧化铪。
