A Catalytic Aldol Reaction between Ketene Silyl Acetals and Aldehydes Promoted by Lithium Amide under Non-acidic Conditions

Abstract
A catalytic aldol reaction between trimethylsilyl enol ethers and aldehydes by using lithium diphenylamide, a Lewis base catalyst, in DMF or pyridine solvent proceeded smoothly to afford the corresponding aldols under mild conditions.
