- an optically active alcohol compound can be taken out by adding water and, if necessary, an organic solvent insoluble in water to the reaction mixture, subjecting to extraction, and concentrating the obtained organic layer.
- the taken out optically active alcohol compound may be further purified by ordinary purification means such as distillation, recrystallization, column chromatography and the like.
- organic solvents insoluble in water examples include aromatic hydrocarbon solvents such as toluene and xylene; aliphatic hydrocarbon solvents such as hexane and heptane; halogenated hydrocarbon solvents such as chloroform and benzene; Examples include ether solvents such as jetyl ether and tert-butyl methyl ether, and the amount used is not particularly limited.
- optically active alcohol compound thus obtained includes optically active 1 monophenoxy 1
- Example 4 except that 4-methoxyphenol was used in place of 3-methoxyphenol, the same procedure as in Example 4 was carried out, except that 1-chlorophenol 3 1 (4-methoxyphenol) 1 2 An oil containing monopropanol was obtained.
- Example 7 In Example 1, in place of phenol, 4 monophenoxyphenol was used, except that optically active 1- (4-phenoxyphenoxy) 1 2-propanol was used in the same manner as in Example 1. An oily substance containing can be obtained.
- Example 7 In Example 1, in place of phenol, 4 monophenoxyphenol was used, except that optically active 1- (4-phenoxyphenoxy) 1 2-propanol was used in the same manner as in Example 1. An oily substance containing can be obtained. Example 7
- Example 2 optically active 1 1 (4-phenoxyphenoxy) 1 2 -propanol was used in the same manner as in Example 2 except that 4 1-phenoxyphenol was used instead of phenol. An oily substance containing can be obtained.
- the asymmetric complex of the present invention exhibits high catalytic activity in the reaction between a cyclic ether compound and a phenol compound, an optically active alcohol compound is produced more advantageously industrially by using the asymmetric complex. be able to.
