79% | With ammonium acetate; In ethanol; at 80℃; for 6h;Microwave irradiation; | General procedure: To a solution of the dinitropyridone 1 (50 mg, 0.25 mmol) in ethanol (10 mL), 4-phenyl-3-buten-2-one (4a) (36.5 mg, 0.25 mmol) and NH4OAc (578 mg, 7.5 mmol) were added, and the resultant mixture was heated at 65 C for 24 h. After removal of the solvent, the residue was washed with benzene (3 × 10 mL) to remove unreacted ketone 4a and treated with column chromatography on silica gel (eluent: hexane/ethyl acetate =95/5) to afford 5-nitro-2-(2-phenylethenyl)pyridine (5a) (41 mg, 0.18 mmol, 72%) as a yellow powder. The reactions of the dinitropyridone 1 with other ketones 4b-f or 10a-c were performed in a similar way. |
