Abstract
一种使用羧基酯酶立体有择水解式(Ⅱ)化合物的(+)和(-)异构体的混合物的方法:
其中R是C1-6烷基;
(i)生成式(ⅢA)化合物,
然后从余下的式(Ⅱ)的(-)异构体中分离出所得的式(ⅢA)化合物;或
(ii)生成式(ⅢB)化合物:
然后从余下的式(Ⅱ)的(+)异构体中分离出所得的式(ⅢB)化合物。
Description
本发明涉及一种新方法和某些新中间体。
该化合物在一些国家已被批准为人用,并且以抗抑郁药出售。
制备paroxetine的所有已述方法包括化学反应,例如美国专利4902801中所述的化学反应。显而易见paroxetine实际上是(一)异构体(如上所示),制备paroxetine的所有化学方法包括化学拆分步骤,它浪费底物和反应试剂,并且必须使用昂贵的拆分试剂,因此它是一个必须进行的相当昂贵的反应。
本发明包括使用酶拆分步骤,其减少或克服了纯化学拆分步骤所产生的一些问题。
(i)生成式(IIIA)化合物,然后从余下的式(II)的(-)异构体中分离出所得的式(IIIA)化合物;或
显然选择羧基酯酶将决定哪种式(II)异构体水解成相应的酸,它可通过例行试验来确定。
优选方法分支(i)。
当使用方法分支(i)时,该方法的立体选择性为在羧基酯酶作用于式(II)化合物的外消旋混合物后,式(II)的(-)异构体与(+)异构体之比,它大于60%,优选地为大于70%,较优选地为大于80%,最优选地为大于85%。
当使用方法分支(ii)时,该方法的立体选择性为在羧基酯酶作用于式(II)化合物的外消旋混合物后,式(II)的(+)异构体与(-)异构体之比,它大于60%,优选地为大于70%,较优选地为大于80%,最优选地为大于85%。
该方法适宜将(±)未拆分的式(II)化合物溶于合适的溶剂如含水的/有机溶剂混合物中,然后加入羧基酯酶,搅拌所得混合物直至反应完成。
进行反应的合适的温度为0-50℃,较合适地为10-40℃,更合适地为25-35℃,最合适地为30℃。
合适的含水/有机溶剂混合物包括缓冲的含水溶剂,如与DMSO混合的三羟甲氨基甲烷缓冲液。
进行反应所需的合适的PH值为PH4至8,较合适为PH5至7,优选PH5.5。
对于可变的R,合适的等同物包括甲基和乙基。优选R是乙基。
术语羧基酯酶是指国际上公认的列于EC3.1.1组的那些酶。
合适的羧基酯酶包括猪肝酯酶和牛肝酯酶,它们均可从市场上购买到,或者用文献中所得方法分别从猪肝或牛肝中提取。
显然由微生物生产的羧基酯酶也适用于本发明。
在方法分支(i)中,羧基酯酶立体有择地水解式(II)化合物的(+)形式,余下的式(II)化合物的(-)形式通过常规方法分离,例如用不含水的可混溶溶剂如乙酸乙酯溶剂萃取式(II)化合物,所得的(-)式(II)化合物可用常规方法如沉淀进行分离。
本发明还涉及接着将上述制备的(-)式(II)化合物转化为paroxetine或其药物上可接受的盐和/或溶剂化合物如盐酸盐半水合物的方法,例如使用美国专利4,902,801和美国专利4,721,723中所列方法。
在方法分支(ii)中,羧基酯酶立体有择地水解式(II)化合物的(-)形式生成式(IIIB)化合物,余下的式(II)化合物的(+)形式可用上述方法从式(IIIA)化合物中分离出来。
式(IIIB)化合物可用常规酯化方法首先转化为(-)式(II)化合物,然后转化为paroxetine。例如使用美国专利4,902,801和美国专利4,721,723所述方法,将该酯转化为parox-etine或其药物上可接受的盐和/或溶剂化物如盐酸盐半水合物。
另外,使用常用的还原剂如氢化铝锂,将羧酸基团还原成羟甲基并且还原哌啶环上的两个酮基,从而使式(IIIB)化合物直接转化为paroxetine。接着例如使用美国专利4,902,801和美国专利4,721,723所述方法,将所得的哌啶甲醇化合物转化为paroxetine或其药物上可接受的盐和/或溶剂化物如盐酸盐半水合物。
可以相信式(IIIA)化合物和式(IIIB)化合物是新的,其任何混合物包括外消旋体也是新的。本发明也涉及式(IIIA)化合物或式(IIIB)化合物,或其盐或水合物,及其任何混合物包括外消旋体。
式(II)化合物可根据美国专利4,902,801中所述方法制备。
下列实施例用来说明本发明。
实施例1(-)反-3-乙氧羰基-4-(4′-氟苯基)-N-甲基哌啶-2,6-二酮
将(±)反-3-乙氧羰基-4-(4′-氟苯基)-N-甲基哌啶-2,6-二酮(1.51g,5.15mmol)的DMSO(100ml)溶液加到三羟甲基氨基甲烷缓冲液(900ml,0.2m,PH5.5)中,再将PH调至5.5。加入猪肝酯酶(Sigma Chemical Co.,19ml,5340单位)。将反应搅拌20小时,通过加入氢氧化钠水溶液(0.105m,25ml,2.63mmol)保持PH不变。
反应混合物用乙醚(3×300ml)萃取,合并的有机萃取液用三羟甲基氨基甲烷缓冲液(0.1M,PH8.5,2×250ml)洗涤,三羟甲基氨基甲烷缓冲液萃取液用乙醚(1×200ml)洗涤,合并的有机萃取液用无水硫酸镁干燥。
在16、18和20小时测试反应混合物。每一次对映体之比为90∶10(-)∶(+)。
蒸发溶液成油状物,用甲苯/THF置换。然后溶液用氢化铝锂还原。含有0.15g还原物质的30mlTHF/甲苯的最终溶液的旋光度为-16.5°。手性HPLC表明异构体之比为86∶14(-)∶(+)。
