The reaction mixture was allowed to stir at reflux for about 3 hours under nitrogen. The reaction mixture was extracted 3 times with dichloromethane; the combined organic layers were washed with brine solution and dried over potassium carbonate. The sample was concentrated on a rotary evaporator and the resulting oil was dried overnight under vacuum. Column chromatography (silica gel, 70:30 hexanes:ethyl acetate) yielded light yellow solid compound 114 (0.581 g, 42percent), mp 98¡ã C.; TLC (silica gel, 30:70 ethyl acetate:hexanes), Rf 0.36; MS (ESI): m/z 369 (39.1), 368 (22.1), 367 (M+H, 100), 273 (3.2), 271 (10.7).

General procedure: Different aniline (0.75 mmol) was dissolved in CH3CN (10 mL) in a 25-mL round-bottomed flask and cooled to 0¡ãC in an ice bath. To this stirred mixture was added t-BuONO (1.125 mmol) followed by TMSN3 (0.9 mmol) dropwise. The resulting solution was stirred at room temperature for 2 h. Compound 2 (0.5 mmol), CuI(0.1 mmol) and Et3N (0.6 mmol) were then added and the reaction was stirred at room temperature. The progress of the reaction was monitored by TLC. After the completion of reaction, the solvent was removed under reduced pressure, and the residue was purified by silica gel column chromatography using petroleum ether/ethyl acetate as eluting solution to afford the target compounds 3 [25?29]. The data of 3a?3w are shown as follows. We selected one compound, 3d, as a representative compound and signal positions of carbon protons were assigned.
