Description
技术领域
本发明属于药物合成技术领域,具体涉及一种恩格列净中间体化合物及其制备方法。
背景技术
恩格列净(empagliflozin),化学名为(2S,3R,4R,5S,6R)-2-[3-[4-[(S)-四氢呋喃-3-基氧基]苄基]-4-氯苯基]-6-羟甲基环氧己烷-3,4,5-三醇,由勃林格殷格翰公司和礼来公司共同开发,2014年5月首次被欧洲药品管理局(EMA)批准上市,它是以不依赖胰岛素分泌和胰岛素作用的机制有效地降低血糖,改善胰岛素敏感性及胰岛β细胞的功能,是首个可降低心血管疾病风险、心脏病及中风的SGLT2类降血糖药物,分子量:450.91,CAS登记号:864070-44-0,结构式如下:
目前,碳-芳基糖苷类SGLT-2抑制剂的的合成路线主要是先制备芳基亲核试剂,再由正丁基锂的作用下对D-葡萄糖内酯进行亲核加成:或者与羟基保护的D-溴代吡喃葡萄糖发生偶联反应得带芳基侧链的糖类关键中间体,中间体进一步脱保护、还原可得恩格列净,如中国专利申请CN105399735以化合物18即5-碘-2-氯苯甲酸为原料,经多步反应得到化合物21,化合物21经硼氢化钠-三氯化铝体系还原得到化合物22,化合物22与正丁基锂、溴化锌-溴化锂反应后与化合物5发生偶联反应,选择性地生成β构象产物23,化合物23在甲醇钠条件下脱去特戊酰基得到目标物I。此法合成路线比较短,反应条件温和,使用特戊酰基保护立体选择性好,收率较高,但使用了价格较高的(S)-3-羟基四氢呋喃,增加了成本:
美国专利US12892310在酸性条件下,化合物21在1,1,3,3-四甲基二硅醚和三氯化铝体系中经还原反应得到化合物22,化合物22与异丙基氯化镁/氯化锂发生格氏试剂交换反应后与中间体3发生亲核加成反应,在柠檬酸的作用下得到化合物24,化合物24在盐酸-甲醇溶液条件下反应得到化合物25,化合物25在三乙基硅烷-三氯化铝作用下脱去甲氧基得到目标物:
此法合成路线比较短、收率高、反应条件温和。但(S)-3-羟基四氢呋喃价格比较贵,增加了合成成本,且该路线后处理比较繁琐。
专利WO2015101916以化合物26即5-碘(或溴)-2-氯苯甲醛为原料,经多步反应得到化合物28;或者化合物26在DMF催化下与草酰氯反应得到化合物32,化合物32在路易斯酸三氯化铝作用下,与氟化苯反应得到化合物33,化合物33在强碱叔丁醇钾作用下,与(S)-3-羟基四氢呋喃发生SN2亲核取代反应,再经硼氢化钠还原得到化合物28。以三乙胺作缚酸剂,用三甲基氯硅保护化合物28的羟基得到化合物29;或化合物28与甲磺酸反应得到化合物34,在-70℃,化合物29(或化合物34)先与正丁基锂发生锂-卤交换,再与化合物3发生亲核加成得到化合物30,用甲磺酸的甲醇溶液使化合物30(或化合物35)的羟基转化成甲醚均得到化合物31,化合物31在三乙基硅烷和三氟化硼乙醚溶液体系中脱去两个甲氧基得到目标物:
此法合成路线比较长,糖基和芳基侧链反应仍没有避开正丁基锂的使用,后处理比较繁琐,且反应条件非常苛刻,不利于工业化生产。
鉴于目前制备恩格列净存在上述问题,研究寻找一条反应条件温和,操作过程简便,产品收率高、纯度高,生产成本低的适合工业化生产的路线是目前需要解决的问题。
