| titleOfInvention | Method for producing optically active quaternary carbon-containing compound |
| abstract | PROBLEM TO BE SOLVED: To produce an optically active quaternary carbon-containing compound by catalytic asymmetric Michael addition reaction. By using an asymmetric catalyst comprising a Lewis acid and an optically active bipyridine compound as a reaction substrate, a β-ketoester compound and a compound having an activated double bond, a Michael reaction is achieved in a high yield. It proceeds with high stereoselectivity, and an optically active quaternary carbon compound of the following formula is produced. [Formula 4] (Wherein R 4 and R 5 together form a 5-membered ring, R 6 is an alkyl group having 1 to 6 carbon atoms, R 7 and R 8 are hydrogen atoms, R 9 is an alkyl group, etc. Represents.) [Selection figure] None |
