Enantioselective Cyano-Alkoxycarbonylation of α-Oxoesters Promoted by Brønsted Acid–Lewis Base Cooperative Catalysts
摘要:
The highly enantioselective cyano-alkoxycarbonylation of alpha-oxoesters with alkyl cyanoformates is promoted by a new chiral Bronsted acid-Lewis base cooperative organocatalyst. The present catalysis can be performed at room temperature under nitrogen or air.
