HBF4 Catalyzed Mannich-Type Reaction in Aqueous Media
摘要:
HBF4 catalyzed Mannich-type reaction took place smoothly in aqueous media to afford beta-amino carbonyl compounds in high yields. One-pot synthesis of beta-amino carbonyl compounds from aldehyde and amine also worked well.
aldimines took place smoothly in aqueous organic solvent to afford β-aminocarbonyl compounds in high yields. The HBF4-catalyzed Mannich-type reaction also proceeded smoothly in water without organic solvent in the presence of a surfactant. A three-component synthesis starting from aldehyde, amine, and silyl enolate was successfully realized by means of a Bronsted acid in aqueous media.
