YieldReaction ConditionsOperation in experiment
Stage #1: N‐(4-bromophenyl)glycine With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; N-ethyl-N,N-diisopropylamine In dichloromethane at 0℃; for 0.5h; Stage #2: (+)-aloperine In dichloromethane at 0 - 20℃; for 12h; General procedure: To a solution of 13a-r (2mmol) in anhydrous CH2Cl2 (30mL) at 0°C, N-hydroxy benzotrizol (HOBt, 2.7mmol), diisopropylethylamine (5.2mL) and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDCI, 4mmol) were added. The mixture was stirred for 30min before the addition of aloperine (2.1mmol), and was warmed to r.t. and stirred for 12h. The mixture was washed with water and brine (30mL), dried over anhydrous Na2SO4, filtered and then the filtrate was concentrated in vacuo. The residue was purified by flash column chromatography on silica gel with CH2Cl2/CH3OH as the eluent to give the products 14a-r.
