实验步骤: A mixture of phenylbutyl formamide (g, 1.5 mmol), triethylamine (6.4 mmol), 4 Å molecular sieves (g), triphosgene (0.8 mmol), and selenium powder (3.0 mmol) in CH2Cl2 was refluxed and worked up as mentioned for 2a. The crude residue thus obtained was purified by silica gel column chromatography (EtOAc/hexanes 2:98) to give 0.96 g (95%) of 2d as an oil. 1H NMR (CDCl3) δ 1.37-1.43 (m, 2H), 1.45-1.51 (m, 2H), 1.67 (dt, 2H, J=15.2 and 7.6 Hz), 1.75 (dt, 2H, J=14.9 and 6.7 Hz), 2.64 (t, 2H, J=7.6 Hz), 3.60 (t, 21-1, J=6.7 Hz), 7.19-7.25 (m, 3H), 7.32-7.40 (m, 2H); HRMS (EI) calcd for C13H17NSe, 267.0521. found, 267.0529. was refluxed The crude residue thus obtained was purified by silica gel column chromatography (EtOAc/hexanes 2:98)
