[2] Nitrogen having larval hormone activity by reacting an alcohol derivative such as 1-methyl-2- (4-phenoxyphenoxy) ethanol in the presence of a base with a halogenated nitrogen-containing heterocyclic compound such as 2-chloropyridine A method for preparing 2- [1-methyl-2- (4-phenoxyphenoxy) ethoxy] pyridine, which is a containing heterocyclic compound, is known (JP 3034951 A). Alcohol derivatives which are intermediates for the preparation, i.e. 1-methyl-2- (4-phenoxyphenoxy) ethanol, have been prepared, for example, by reacting propylene oxide with 4-phenoxyphenol in the presence of a base. However, in this process, not only the desired 1-methyl-2- (4-phenoxyphenoxy) ethanol is produced, but also its isomer 2-methyl-2- (4-phenoxyphenoxy) ethanol as a byproduct. do. Therefore, it is necessary to separate and remove the isomers using separation techniques such as crystallization. For this reason, from an industrial point of view the method has not always been considered a very satisfactory method.
[3] In addition, for the preparation of optically active nitrogen-containing heterocyclic compounds, organic carboxylic acid esters of the alcohol derivatives are treated with microbial induced esterases to cause asymmetric hydrolysis and to supply optically active alcohol derivatives. As the number of manufacturing steps is increased, this is not always very satisfactory from an industrial point of view.

Trialkoxy aluminum may include triethoxy aluminum, triisopropoxy aluminum and tri-tert-butoxy aluminum. Titanium halides may comprise titanium tetrachloride. Tetraalkoxy titanium may comprise tetraisopropoxy titanium. Boron halides may include boron trifluoride, boron trichloride and boron tribromide. Zinc halides can include zinc chloride and zinc bromide.
[231] Lewis acids can be used on their own or in solutions in organic solvents. For example, Lewis acids, which are unstable to air or water and require careful handling, are preferably used as solutions in organic solvents. As long as the organic solvent is inert to Lewis acid, the organic solvent is not particularly limited, and may include aliphatic hydrocarbon solvents such as hexane and heptane; And ether solvents such as diethyl ether and tert-butyl methyl ether. In addition, complexes of Lewis acids such as boron trifluoride-diethyl ether complex may also be used.
[232] The amount of Lewis acid used is not particularly limited, but is usually 0.2 to 5 moles, preferably 0.5 to 2 moles per 1 mole of the metal complex (1).
[233] The metal complex catalyst of the present invention can be produced by reacting the metal complex 1 with Lewis acid, and the reaction is usually carried out in an organic solvent by contacting and mixing them. When they are contacted and mixed, a reaction occurs to form new complexes. The preparation of new (asymmetric) complexes is achieved, for example, by mixing them in an organic solvent, where the mixing has caused a color change in the reaction mixture such that the metal complex reacted with Lewis acid to form a new (asymmetric) complex. It allows you to check. For example, (-)-N, N'-bis (3,5-di-tert-butylsalicylidene) -1,2-cyclohexanediamino cobalt (III) 4-phenoxyphenolate is tert- When mixed with aluminum chloride in butyl methyl ether, the color of the mixture changes from brown to dark green.

[236] For example, if water is present in the reaction system, the Lewis acid is easily decomposed, and therefore, it is preferable to dehydrate the reactants, solvents and the like used in advance, or to allow a dehydrating agent such as molecular sieve to coexist in the reaction system.
[237] When the metal complex (1) is reacted with Lewis acid in an organic solvent, in the reaction between the cycloether compound (2) and the phenol derivative (3), a solution containing the resulting novel complex catalyst can be used by itself, Or the novel complex catalyst can be separated before use, for example by the concentration of the solution.
[238] In this step, an asymmetric complex catalyst can be obtained by using a metal complex of formula 1 'or 1'a. By reacting the cyclic ether compound (2) with the phenol derivative (3) in the presence of the catalyst, a desired optically active alcohol derivative can be obtained by a reaction showing excellent position and stereoselectivity.

[257] The amount of the cyclic ether compound used is usually 1 mol or more (2 mol or more when an asymmetric complex catalyst is used) per 1 mol of the phenol derivative, and there is no specific upper limit thereof. Too large an amount easily results in economic losses, so the amount is usually 5 moles or less (10 moles or less, if an asymmetric complex catalyst is used).
