80%; 10% | With aluminum oxide; In neat (no solvent); at 95℃; for 3.0h;Green chemistry; | General procedure: The amine (7.5 mmol) and the Michael acceptor (5 mmol) in a molar ratio of 1.5:1 were refluxedwith stirring in the presence of acidic alumina (1 g, 200 mol%). Heating was performed using an oilbath and the reaction was followed by TLC and GC until completion. The reaction was then allowedto cool down to room temperature and filtered through a filter paper. The catalyst was rinsed withethyl acetate/hexane and then concentrated by rotary evaporation. The crude reaction mixture waspurified using a silica-filled chromatographic column using hexane/ethyl acetate as eluents. Usually,for aliphatic amines, the mono-adduct was eluted using 7:3, 6:4 or 5:5 hexane/ethyl acetate whilstfor aromatic ones the solvent mixture used was 8:2 hexane/ethyl acetate. The yields of the purifiedproducts were recorded and then IR and NMR spectroscopy and MS spectrometry were performed. |
