烯丙基丙二酸二乙酯是一种有机中间体,可由丙二酸二乙酯与烯丙基溴反应得到。有文献报道其可用于制备一种中华按蚊用杀虫剂。
制备过程 在氮气气氛下,向500 mL三颈圆底烧瓶中加入20 g 丙二酸二乙酯、43 g 无水碳酸钾和200 mL 无水CH₃CN。将反应混合物在室温搅拌10分钟后,在室温下缓慢加入23 g 烯丙基溴。随后,将反应混合物加热至80℃并保持24小时。冷却后,通过硅藻土床过滤,并用乙腈(100 mL)洗涤硅藻土床。合并滤液并浓缩得到24 g 烯丙基丙二酸二乙酯,为无色液体。
用途 烯丙基丙二酸二乙酯可用作医药原料和农药中间体。

A convenient synthesis of DL-hydroxy-ornithine is described. Starting from diethyl allylmalonate, it involves treatment with sulphuryl chloride followed by hydrolysis and distillation to give a 90% yield of 2,5-dichloro-4-valerolactone. Condensation of this with two equivalents of potassium phthalimide in dimethyl-formamide gives a quantitative yield of crude 2,5-diphthalimido-4-valerolactone. This lactone is converted quantitatively by acid hydrolysis to DL-γ-hydroxyornithine, isolated as the dihydrochloride of the corresponding 2,5-diamino-4-valerolactone. The over-all yield calculated from allyl chloride is 80%.
