3-(2-(2-Azidoethoxy)ethoxy)prop-1-yne

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

实验步骤: 3-(2-(2-azidoethoxy)ethoxy)prop-1-yne (s-4) (2 g, 11.82 mmol, 1.0 equiv) was dissolved in THF (30.5 mL). Triphenylphosphine (3.72 g, 14.20 mmol, 1.2 equiv.) and water (0.21 mL, 11.83 mol, 1.0 equiv.) were added to the solution and the reaction was allowed to stir at room temperature for 10 hours. The reaction was concentrated under reduced pressure and chromatographed (5% CH3OH in CHCl3, then 5% CH3OH in CHCl3+5% Et3N) to yield 2-(2-(prop-2-ynyloxy)ethoxy)ethanamine (s-5) as a pale green oil (1.35 g, 80%).

HRMS (ES+) calc'd for C7H13NO2 (M+H) m/z 144.0980 Found 144.1019. The reaction was concentrated under reduced pressure chromatographed (5% CH3OH in CHCl3
