| titleOfInvention | Method for preparing asymmetric synthesis catalyst |
| abstract | (57) Abstract: A novel method for preparing an optically active binaphthol rare earth metal complex useful as an asymmetric synthesis catalyst is provided without excessive use of an expensive rare earth metal compound. SOLUTION: In a solvent in which finely powdered rare earth metal trichloride hydrate is dispersed, a compound of the formula (IR): Or formula (IS) (R1 and R2 each independently represent hydrogen, an alkyl group, a phenyl group, etc., and the position of R1 is 3, 4, 5, The sixth and seventh positions and R2 may be anywhere from the 3 ', 4', 5 ', 6'and 7'positions. ) Optically active 1,1'- A catalyst for asymmetric synthesis of an optically active 1,1′-bi-2-naphthol metal complex, characterized by mixing a bi-2-naphthol derivative dilithium salt for reaction, and then adding an alkali metal compound for reaction Method of preparation. |
