AbstractA three-componentMannich-typereaction of aromatic aldehydes, aromatic amines, and ketones was catalyzed by a novel functionalized ionic liquid, 3-(N,N-dimethyldodecylammonium)propanesulfonic acid hydrogen sulfate ([DDPA][HSO4]) at room temperature to give various β-amino carbonyl compounds in good yields. The catalyst could be reused at least six times without noticeably reducing catalytic

AbstractSnCl2-catalyzed three-component one-pot Mannich reaction of acetophenone or p-chloroacetophenone with different aromaticaldehydes and aromatic amines in ethanol at ambient temperature gave the corresponding β-aminocarbonyl compounds in good to excellent yields. Four new compounds are reported for the first time. Graphical abstract
