Description
技术领域
本发明属于药物中间体合成领域,具体来说是涉及一种阿维巴坦关键中间体(2S,5R)-5-[(苄氧基)氨基]-哌啶-2-甲酸乙酯的合成方法。
背景技术
阿维巴坦是一种新型β-内酰胺酶抑制剂,可以长效的与酶可逆性共价结合,且不会诱导β-内酰胺酶产生,属于二氮杂双环辛酮化合物,与各类头孢菌素和碳氢霉烯抗生素联合使用时,具有广谱抗菌活性。阿维巴坦化学名称为:[(1R,2S,5R)-2-(氨基羰基)-7-氧代-1,6-二氮杂双环[3.2.1]辛-6-基]硫酸单酯。而(2S,5R)-5-[(苄氧基)氨基]-哌啶-2-甲酸乙酯是制备阿维巴坦的关键中间体,该类化合物具有两个手性中心,合成难度大,广泛用于阿维巴坦和其他生物活性物质的制备,但由于目前价格昂贵,限制了其在药物合成中的应用。
专利WO2012172368A(CN103649051A)公开(2S,5R)-5-[(苄氧基)氨基]-哌啶-2-甲酸乙酯的合成方法,如反应式一所示:
反应式一
该方法以Boc-L-焦谷氨酸乙酯为起始原料,经碱性开环、亚胺化、脱保护、碱性关环、还原、拆分得到(2S,5R)-5-[(苄氧基)氨基]-哌啶-2-甲酸乙酯。在脱保护步骤,使用甲磺酸(MSA),容易产生较大的杂质,使用碳酸氢钾进行关环时,反应放热非常明显,反应时间对反应影响较大,不适合大规模生产。
专利US20130296555公开了(2S,5R)-5-[(苄氧基)氨基]-哌啶-2-甲酸乙酯的另一种合成方法,如反应式二所示:
反应式二
