Description
技术领域
本发明属于药物化学领域,涉及抑制KRAS G12D或KRAS G12C的化合物的关键中间体的制备,具体涉及一种((2R,7aS)-2-氟六氢-1H-吡咯嗪-7a-基)甲醇的制备方法。
背景技术
KRAS基因突变是人类癌症中最常见的一种激活突变,90%的胰腺癌,40%的结肠癌,20%的肺癌中都存在这种基因突变。由于KARS蛋白球形平滑的空间结构和GTP皮摩尔级的极强亲和力,使其成为极难成药的靶点。KARS G12D突变为12位密码子的甘氨酸(G)被末端为羧酸的天冬氨酸(D)取代,目前还没有针对该靶点的药物上市,但是WO2022105859A1、WO2022098625A1、WO2022015375A1/WO2021041671A1、WO2021139748A1、WO2022002102A1和WO2022031678A1专利公开该靶点新化合物,均含有有下式I片段。
KRAS G12C突变为12位的甘氨酸被半胱氨酸替换的突变,其中WO2020146613 A1、WO2022081655A1、WO2021180181A1和WO2021259331A1公开的该靶点抑制剂也均含有式I片段。WO2021139748螺环四氢喹唑啉KRAS抑制剂也含有该片段、CN114031562A/CN114057776A公开了选择性抑制KRAS突变的抑制剂化合物,也含有式I片段,保护两条不同制备工艺。
CN114615981A(WO2022015375A1/WO2021041671A1)公开合成路线如下所示:
该路线总体收率较低,只有3.5%,且涉及臭氧化和手性色谱拆分等难以在放大生产中实施的步骤,因此难以工业化。
WO2022002102A1公开合成路线如下所示:
该专利从手性氟代原料出发经过九步得到目标产物,涉及不同还原剂进行多次还原和Dess-Martin过碘酸酯氧化,生产成本高,同时该反应路线未提及收率和选择性。
综上所述,现有技术报道的方法存在步骤繁琐、反应条件苛刻、成本高、收率低等诸多问题;因此,仍需开发操作简便、安全性高、成本低、选择性好、收率高、适合工业化放大量生产的((2R,7aS)-2-氟六氢-1H-吡咯嗪-7a-基)甲醇高效生产方法。
发明内容
