a. 在氮气保护下,将N-叔丁氧羰基-4-哌啶酮(50 g, 0.25 mol)和锌粉(49.2 g, 0.75 mol)悬浮于四氢呋喃(500 mL)和氯化铵水溶液(2/3, 500 mL)的混合溶液中。控制反应温度在-10至10℃之间,缓慢滴加3-溴-1-丙烯(109.3 g, 0.90 mol)。滴加完毕后,缓慢升温至15-40℃,继续搅拌反应2-5小时。通过薄层色谱(TLC,展开剂比例为石油醚/乙酸乙酯=2/1,体积比)监测反应进度。反应完成后,用乙酸乙酯(100 mL×3)萃取反应混合物。合并有机相,用无水硫酸钠干燥,过滤后减压浓缩,得到粗产物。粗产物通过硅胶柱色谱纯化(洗脱剂比例为石油醚/乙酸乙酯=30/1至10/1,体积比),得到无色油状目标化合物4-烯丙基1-Boc-4-羟基哌啶(60 g),收率为99.9%。
