Abstract
本发明公开了不对称催化氢化制备沙库巴曲化合物的方法,是一条具备工业化的生产路线。本发明通过不对称催化氢化反应合成沙库巴曲化合物的路线为:
Description
技术领域
本发明属于药物合成领域,具体涉及沙库巴曲的制备方法。
背景技术
沙库巴曲,化学名(2R,4S)-4-(3-羧基-1-氧代丙胺)-5-([1,1’-联苯]-4-基)-2-甲基戊酸乙酯,其合成路线已有公开分别如下:
Ciba Geigy Corporation公司于1992年1月22日申请的US5217996公开了叔丁氧羰基-D-酪氨酸甲酯32与三氟甲磺酸酐(Tf2O)反应得33,33在三苯膦钯催化下与苯基硼酸发生Suzuki偶联制备得到34,34经水解反应制备得到羧酸35,35与甲氧基甲胺反应生成Weinreb酰胺36,36经氢化锂铝反应制备得到醛37,37与乙氧甲酰基亚乙基三苯膦发生Wittig反应得烯烃30。30经Pd/C催化氢化制备得到31,所得31非对映异构体比例为(2R,4S):(2S,4S)=80:20,31在盐酸条件下脱Boc保护基制备得到19,19与丁二酸酐酰化并进一步酯化成叔丁酯,用硅胶柱层析分离去除叔丁酯的非对映异构体,最后水解叔丁酯、纯化得到沙库巴曲(Sacubitril)的方法。具体反应方程式为:
期刊文献中国医药工业杂志2017,48(9)页1266中公开了由D-苯丙氨酸经碘代、甲酯化、氨基保护、Negishi偶联、硼氢化锂还原、TEMPO催化氧化、缩合、氢氧化锂水解、钯碳催化氢化还原后、经脱保护、乙酯化和丁二酸酐缩合制备。
该工艺以钯碳作为氢化反应的催化剂,制备得到的非对映异构体比例为(2R,4S):(2S,4S)=81:19,对映选择性低,达不到工业化的要求。
专利ZL201710294596.4(申请日:2017-04-28,申请人:江苏阿尔法药业有限公司)公开了如下合成路线:
由联苯丙胺醇与4-氯-4-氧代丁酸苄酯经酰胺化反应后,经氧化反应,后与乙氧甲酰基亚乙基三苯基膦进行缩合反应,后经过贵金属催化剂如钯碳等进行氢化反应制备沙库巴曲化合物的工艺。
该工艺中也是用钯碳催化剂氢化反应底物,但并未公开制备得到的非对映异构体比例数值。
上述现有技术中均是使用钯碳作为氢化反应催化剂参与非均相氢化反应,均存在非对映异构体比例比较低,不能达到工业化要求的缺陷。鉴于沙库巴曲化合物有两个手性中心,得到纯的(2R,4S)手性产物是具备一定技术难度的,现有技术中存在的技术问题主要有:1、在制备得到高纯度手性纯度产物上,非对映选择性差、总收率低;2、不能实现工业化生产。为了解决这些技术问题,有必要进一步进行工艺开发,以获得更加具备技术优势的路线。
本发明提供了一种不对称催化氢化反应制备沙库巴曲化合物的合成工艺。该合成工艺收率高、立体选择性好、适合工业化生产。
