NEW CHIRAL ZIRCONIUM CATALYST AND METHOD FOR PRODUCING OPTICALLY ACTIVE ANTI-alpha-METHYL-beta-AMINOCARBONYL COMPOUND |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for producing an α-methyl-β-aminocarbonyl compound in high anti-selectivity and in high enanthio selectivity. <P>SOLUTION: This method for producing the α-methyl-β-aminocarbonyl compound comprises reacting an imine with a silicon enolate in the presence of a new chiral zirconium catalyst represented by formula (I) (X is an electron- attracting group). <P>COPYRIGHT: (C)2003,JPO |
