Claims9
An optically active catalyst composed of a transition metal catalyst and an optically active amine derivative represented by any one of the following formulas:
- wherein R9, R10, R15 and R16 are independently hydrogen, a saturated or unsaturated hydrocarbon group, urethane group or sulfonyl group;
- R11, R12, R13 and R14 are the same or different so that the carbon bonded with these substituent groups might occupy the asymmetric center and independently represent hydrogen atom, an aromatic group, a saturated or unsaturated hydrocarbon group or cyclic hydrocarbon group;
- any one of R11 and R12 and any one of R13 and R14 are bonded together to form a ring;
- at least one of R17 and R18 is hydrogen atom, and the remaining one is hydrogen atom, a saturated or unsaturated hydrocarbon group, urethane group or sulfonyl group;
- R19, R20, R21 and R22 are the same or different so that the carbon bonded with these substituent groups might occupy the asymmetric enter and independently represent hydrogen atom, an aromatic group, a saturated or unsaturated hydrocarbon group or cyclic hydrocarbon group;
- R23 represents hydrogen atom, an aromatic group, a saturated or unsaturated hydrocarbon group or cyclic hydrocarbon group;
- furthermore, any one of R19 and R20 and any one of R21 and R22 may be bonded together to form a ring or any one of R17 and R18 and any one of R20 and R21 may be bonded together to form a ring;
- R24 and R25 are independently hydrogen atom, a saturated or unsaturated hydrocarbon group, urethane group, sulfonyl group or acyl group;
- (CR226)n are the same or different so that the carbon bonded with these substituent groups might occupy the asymmetric center;
- R26 represents hydrogen atom, an aromatic group, a saturated or unsaturated hydrocarbon group or cyclic hydrocarbon group;
- R27 and R28 independently represent hydrogen atom, and or a saturated or unsaturated hydrocarbon group.
