2-(1-溴环丙基)乙醇

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

实验步骤: To a solution of the cyclopropyl alcohol (Step A) (1.303 g, 7.95 mmoles) in 30 ml anhydrous DCM was added anhydrous pyridine (1.2 ml, 1.1736 g, 14.8 mmoles), TBSOTf (2.7 ml, 3.1077 g, 11.76 mol) and the solution was stirred at room temperature for 16 h. It was extracted with CHCl3/brine and the organic fraction was dried with MgSO4. The solvent was reduced and the crude product purified using flash-column chromatography (CHCl3/hexanes 1:10, Rf=0.4). Yield: 0.796 g, 36%. 1H-NMR (500 MHz, CDCl3): δ=3.95-3.75 (t, 2H), 1.95-1.85 (t, 2H), 1.15-1.05 (m, 2H), 0.95-0.80 (m, 11H), 0.15-0.05 (s, 6H). It was extracted with CHCl3/brine the organic fraction was dried with MgSO4 the crude product purified
