2-碘-N-甲基乙胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: This compound was prepared using N-methyl-N-2-iodoethylamine.HI via N-methyl-N-(2-iodoethyl)phosphoramidic dichloride, as described for 16a (10 mmol scale). The crude product was purified by chromatography (1:4 EtOAc:hexanes) which afforded 16c as a pale yellow oil (2.50 g, 61%): Rf 0.67 (1:1 EtOAc:hexanes); 1H NMR (CDCl3) 4.27(m, 3H), 4.10(t, 1H, J=6.52 Hz), 3.59(t, 1H, J=7.38 Hz), 3.44(m, 2H), 3.26(t, 2H, J=7.56 Hz), 2.78(d, 3H, J=12.89 Hz), 2.00(dt, 2H, J=6.02 Hz), 1.38(d, 6H, J=15.48 Hz)ppm; 31P NMR (CDCl3) -8.46, -8.69 ppm (1:1 ratio of diastereomers). This compound was prepared The crude product was purified by chromatography (1:4 EtOAc:hexanes) which
