Brønsted Acid-Catalyzed Mannich-Type Reactions in Aqueous Media
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.

Use of boron trifluoride etherate and trichloromethylsilane in the presence of zinc-copper couple effects a crossed imino pinacol coupling reaction to give 1,2-diamines in good yields with high diastereoselectivities.
On treatment of aldimines derived from aromatic aldehydes and aniline with allylsilane in the presence of Lewis acid, [4+2] cycloannulation took place smoothly to afford tetrahydroquinoline derivatives in moderate to good yields.
