The reactions of enolizable carbonyl compounds with azomethine functions, usually referred to as Mannich-type reactions (also termed aza ± aldol reactions), result in the formation of b-amino acids, ketones, or aldehydes. [1] These reactions are conceptually equivalent to the aldol reactions, but, i
