| titleOfInvention | A novel ruthenium complex having an amino acid as a ligand and an asymmetric hydrogenation method using the same |
| abstract | (57) [Problem] To provide a less expensive and industrially usable complex as a catalyst used in a hydrogen transfer type reduction reaction as compared with a conventional catalyst. SOLUTION: Formula (I) (R 1 represents H, lower alkyl, methanesulfonyl, p-toluenesulfonyl, trifluoromethanesulfonyl, camphorsulfonyl, acyl, benzoyl; R 2 represents lower alkyl, phenyl, benzyl, aryl, aralkyl, or R 1 and R Form a carbocyclic ring with 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 each represent H, lower alkyl or lower alkoxycarbonyl, and X represents halogen), and an amino acid-ruthenium complex represented by the formula (II): Embedded image Wherein Ar represents phenyl which may have a substituent and naphthyl which may have a substituent, wherein the aromatic ketone is subjected to an asymmetric hydrogenation reaction by a hydrogen transfer type reduction reaction. Formula (III) characterized by the following: (Wherein Ar has the aforementioned meaning) |
