Description

一种关于α-环丙氨酸的制备方法
技术领域
本发明属于有机合成技术领域,具体涉及一种α-环丙氨酸的制备方法。 
背景技术
α-环丙氨酸是一种天然非蛋白特种氨基酸,在医药和食品上用途很大。ACC能防治老年痴呆、保护脑神经损伤和降血压等作用;在养殖业上能调控家蚕蛋白生物合成,调控家禽产蛋率等;同时对谷类具有优良的生长调控作用,并且具有杀菌、抗肿瘤等作用。但人工合成不是很简单,原料易得、条件温和、方法简单的合成方法就更难。
目前在国内报道的合成方法极少,国外也多为实验室制法,原料不易得,污染大,或反应条件苛刻,收率很低。专利US5569781 A1报道以1,1-环丙基二甲酸二甲酯为原料,与氯化氢、氢氧化钠、氨反应生成所需要的产物,同时生成异构体,影响产率。
    专利US4298760 A1报道中使用原料经过反应,同时使用1,2-二氯乙烷最终生成产物,但中间使用的六甲基磷酰胺,正丁基锂作为实验中出现是可以的,但在放大生成,就会增加生产成本。
Logusch ,EW(Tetrahedron  Letters,1986,第一卷,27,第49页,5935-5938)曾报道:以1-肽酰亚胺基-1-环丙基甲酸甲酯为原料,在氯化氢通暖气的条件下反应,得到ACC。虽然诸如此类的反应很多,但有一个共同缺点,原料很难得到。
目前虽然有些实验可合成α-环丙氨酸,但大规模生成的极缺,寻找一条效益高、污染小、有望扩大生产的合成方法具体重要意义。
