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.

In the presence of a catalytic amount of Bi(OTf)(3).4H(2)O, aldehydes together with amines react with silylenolates to afford the corresponding Mannich-type adducts smoothly. A wide variety of silylenolates derived from ketones, as well as esters and thioesters, react rapidly to afford the beta-amino ketones or the beta-amino esters in high yields (up to 94%).
