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.
HBF4催化的甲硅烷基烯醇化物与醛亚胺的曼尼希型反应在水性有机溶剂中顺利进行,以高产率得到β-氨基羰基化合物。在表面活性剂存在下,HBF4催化的曼尼希型反应在没有有机溶剂的水中也能顺利进行。借助布朗斯台德酸在水性介质中成功实现了从醛、胺和烯醇甲硅烷基开始的三组分合成。
