Method for Producing Optically Active 2-Pyrrolidone Compound |
| abstract |
【Task】 An object of the present invention is to provide a novel method for producing an optically active 2-pyrrolidone compound useful as a pharmaceutical intermediate. SOLUTION: By reacting the ketone compound represented by the formula (3-R) with an ammonium salt and hydrogen gas in the presence of an optically active ruthenium complex catalyst, the formula (1-RR) can be efficiently and highly selectively performed. ), A novel production method for obtaining an optically active 2-pyrrolidone compound.
