反应详情

To a mixture of 1-(methoxymethyl)-3-methylenecyclobutanecarbonitrile (1.40 g, 0.0102 mol) in methylene chloride (30 mL, 0.4 mol) was added 1.0 M of boron tribromide in methylene chloride (12.8 mL) at −78° C. The reaction was stirred at rt for 2 h, quenched with aq. sodium bicarbonate, and extracted with dichloromethane. The combined organic layers were dried over magnesium sulfate and evaporated to dryness to give the desired product (1.26 g, 100%). 1H NMR (400 MHz, CDCl3): 4.81 (2H, m), 3.66 (2H, s), 3.10 (2H, m), 2.59 (2H, m) ppm.
