Using the new chiral salen catalytic converter and this, the chiral salen catalytic converter which is shown with useful below-mentioned formula

摘要

(57) Abstract Topic Offer the new chiral salen catalytic converter where inactivation of the catalytic converter and racemization of the kiraru product by the catalytic converter are difficult to happen. Solutions Solid adding water resolution racemic epoxide choice making use of the chiral salen catalytic converter which is shown with the below-mentioned formula 1, and this, kiraruepokishido or kiraru 1,2 - the manner which produces diol. Conversion 1 Intype 1 type 1, as for X₁ - X_{8 the} hydrogen atom or the alkyl group of C₄ - C₁₀; As for Y₁ and Y₂ hydrogen atom, alkyl group of C₁ - C₅, as for Z PF₆, or BF₄; R₁ and R_{2 the} hydrogen atom, the alkyl group, or the non displacement phenyl group or C₁ - C₄ alkyl displacement phenyl groups of C₄ - C₁₀, is R₁ and the one of R_{2 the} hydrogen atom always, in addition R₁ and R₂ joins mutually, - (CH₂) _n- (as for n integer of 3 - 6) or - (CH₂) it is possible to form m-Q- (CH₂) _m- (as for m to be integer 1 - 2, as for Q oxygen atom or NH).
