Description

一种西格列汀的中间体化合物的制备方法 技术领域
本发明属于药物化学合成技术领域,具体地说,涉及一种西格列汀的中间体化合物的制备方法。
背景技术
西格列汀(英文名:Sitagliptin),化学名为:7-[1-氧代-3R-3-氨基-4-(2,4,5-三氟苯基)丁基]-3-三氟甲基-5,6,7,8-四氢-1,2,4-三唑[4,3-a]吡嗪,如结构式1所示。西格列汀是美国默克公司研制开发的一种二肽基肽酶-IV(DPP-IV)抑制剂,临床上用于治疗II型糖尿病。
Figure PCTCN2014000832-appb-000001
在西格列汀制备过程中,手性氨基的构建为合成路线的要点。目前,西格列汀制备方法中,主要的构建手性氨基的方法如下:
路线一:(参考文献:WO2004/085378)
Figure PCTCN2014000832-appb-000002
该路线中,西格列汀手性氨基的构建是通过金属铑和手性二茂铁基二膦参与的氢化还原反应实现的。该方法主要的缺点是用了金属铑和手性二茂铁配体这两个非常昂贵的试剂,成本大大增加,难以适合工业化大生产。
路线二:(参考文献:WO2004/085661)
Figure PCTCN2014000832-appb-000003
该路线中,通过引入S-苯甘氨酰胺作为手性助剂,氧化铂催化氢化诱导出所需要的手性氨基,再通过脱苄基得到西格列汀。该方法的缺点同样是由于催化剂氧化铂为贵重金属,提高了路线的成本,难以适合工业化大生产。
路线三:(参考文献:WO2009/085990)
Figure PCTCN2014000832-appb-000004
该路线用手性助剂R-α-甲基苄胺代替S-苯甘氨酰胺,但同样用价格昂贵的氧化铂做催化剂进行诱导得到手性氨基。
虽然现有技术已经报导了几种制备西格列汀的方法,但是,它们具有一种或多种缺点,如使用昂贵试剂(氧化铂、铑催化剂等),增加保护和脱保护步骤等。因此开发简单、经济并且可以工业化大生产的合成路线是十分必要的。
发明内容
为了克服现有的制备一种西格列汀的关键中间体的方法中,需使用价格昂贵的试剂,导致成本很高,不适于工业化大生产的缺陷,本发明的目的在于提供一种与现有技术完全不同的式I所示的西格列汀的中间体化合物的制备方法。
为了实现上述目的,本发明提供了一种式I所示的西格列汀的中间体化合物的制备方法,所述制备方法包括:将式II所示的化合物溶于有机溶剂中,在C1~C6饱和脂肪酸的催化下,在氯代硅烷的作用下,进行碳碳双键的还原反应得到式I所示的西格列汀的中间体化合物,化学反应方程式如下所示:

本发明中,所述还原反应的各条件,除上述特别说明的以外,都可按照本领域此类还原反应中的条件进行。
待所述还原反应结束后,可通过简单的后处理,如淬灭、萃取、洗涤、干燥、浓缩即可得到式I所示的西格列汀的中间体化合物。
优选地,所述制备方法还包括从醇或醇与烷烃的混合物中结晶析出式I所示的西格列汀的中间体化合物。
优选地,所述醇为甲醇、乙醇或异丙醇,所述烷烃为石油醚、正己烷或正庚烷。
尽管,本发明的式I所示的西格列汀的中间体化合物也可通过常 规的脱除苄基的方法制得西格列汀,例如,可以参照本申请背景技术中,路线二或路线三涉及的文献中制备西格列汀的方法,或者参照文献WO2004/085378来制备西格列汀。
尽管,本发明的式II所示的化合物也可参照现有技术的方法制备。如,当式II所示的化合物中R为氨甲酰基时,可参考文献WO2004/085378制备,当式II所示的化合物中R为甲基时可参考文献WO2009/085990制备。
