Description

一种合成酰胺类化合物的方法
(一)技术领域
本发明涉及一种合成酰胺类化合物的方法。
(二)背景技术
酰胺是药物分子中非常常见的结构单元,据统计,合成酰胺的反应占药物合成反应类型的16%。特别是N-芳基酰胺,广泛存在于药物分子结构中,例如阿伐他汀、伊马替尼、乙丙昔罗等。合成N-芳基酰胺最常用的方法是酰氯与芳胺在碱的作用下脱除氯化氢。酰氯的合成需要用到有毒和刺激性的氯化试剂。与之相比,羧酸和芳胺直接缩合反应是合成N-芳基酰胺更加环境友好的方法。但是,由于N-芳基酰胺的亲核性比较弱,常见的缩合试剂如三苯基二氯化膦、HATU、 DCC、HOBt等效果均不理想。目前用于羧酸和芳胺直接缩合的缩合试剂有硼酸,三苯基磷/N-氯代邻苯二甲酰亚胺(ACS Omega.0c02309)等,这些缩合试剂均存在反应条件苛刻或原子经济型差等缺点。因此,本发明公开了一种羧酸和芳胺直接缩合的新方法,该反应对芳香酸、脂肪酸和氨基酸等羧酸都适用。反应以特戊酸酐为缩合剂,在温和条件下进行,具有操作简单、产率高、反应速度快、普适性好等优点。
(三)发明内容
本发明的目的是提供一种合成酰胺类化合物的方法,无需添加催化剂,使用有机溶剂,温度在15-80℃条件下反应3-10h,TCL监测反应进程,待反应结束后处理完成即可得到目标产物酰胺。
本发明采用的技术方案是:
本发明提供一种合成酰胺类化合物的方法,所述方法为:将式II所示羧酸类化合物、式III所示芳胺类化合物和特戊酸酐溶于有机溶剂中,15-80℃反应3-10h,所得反应液经后处理,得到式I所示酰胺类化合物;所述式II所示羧酸类化合物、特戊酸酐与式III所示芳胺类化合物的物质的量之比为1.1-1.5:1.1-1.6:1,优选1.1:1.3:1;
Figure RE-GDA0003933432170000011
其中,R1选自下列基团之一:苯基,被C1~10烷基、C1~10卤代烷基、C1~5烷氧基、卤素、氰基、硝基或甲磺酰基取代的苯基,噻吩基,苯并呋喃基,C1~15烷基,取代C1~15烷基,C2~10烯烃基、被苯基取代的C2~10烯基、

R2为氢、甲基或乙基,R3为苯基、被C1~4烷基、C1~4卤代烷基、C1~4烷氧基、卤素、氰基或C1~4烷氧羰基取代基的苯基;或者R2与R3连接成环,并与二者之间的N形成四氢喹啉基。
对于该体系中90%的底物温度在15-50℃即可完成反应,优选50℃,较少空间位阻比较大的底物升高温度转化率会更高。所述反应时间为3-10h,该体系中大部分底物在上述较优条件下反应3-5h(进一步优选4h)即可,少量空间位阻较大等相对比较难反应的底物需要延长反应时间。
在本发明的实施例中,所述式I所示酰胺类化合物为下列之一:
Figure RE-GDA0003933432170000022
进一步,所述有机溶剂为甲苯、乙腈、二氯甲烷、二氯乙烷、乙酸乙酯、四氢呋喃中的一种或两种以上的混合物,优选甲苯。所述有机溶剂为干燥除水后的。
进一步,所述有机溶剂的体积以式III所示芳胺类化合物的物质的量计为 1-5mL/mmol(优选3mL/mmol)
进一步,所述后处理为:所述反应液依次用2mol/L氢氧化钠水溶液、2mol/L 盐酸洗涤、饱和食盐水洗涤,所得有机相用无水硫酸钠干燥,旋蒸除去溶剂,得到式I所示酰胺类化合物。
与现有技术相比,本发明有如下有益效果:
(1)该体系的机理是:底物酸与特戊酸酐反应生成新的酸酐,该酸酐与胺反应生成酰胺,无需添加额外的催化剂,反应高效,试剂廉价易得,操作简单,条件温和;
(2)本发明利用底物酸与特戊酸酐混合形成新的酸酐制备酰胺,该反应底物普适性好,可以合成多种酰胺类化合物;
(3)本发明用特戊酸酐进行活化,无需添加催化剂,反应高效,解决了合成酰胺的反应过程中所产生的副产物后处理问题;

通过混合酸酐形成酰胺键是合成酰胺化合物最古老的方法之一,常见的酸酐有:羧酸酸酐、碳酸酸酐、Boc酸酐、磺酸盐混合酸酐、磷酸类混合酸酐。混合羧酸酸酐一般是由试剂与乙酸酐或特戊酰氯形成,缺点是形成的常为混合物,可能为两种对称的酸酐,如乙酸酐与试剂反应产生的混合酸酐与胺反应的区域选择性较差;混合碳酸酸酐是羧酸与氯甲酸盐或EEDQ(2-乙氧基-1-乙氧碳酰基-1,2- 二氢喹啉)等试剂反应形成酸酐,制备这些混合羧酸酸酐和碳酸酸酐通常需要在碱的存在下将试剂加入到羧酸溶液中。Boc酸酐较少用于活化酰胺的试剂,因为该试剂熔点较低(23℃),而反应通常在较低温度下进行。甲基磺酰氯和对甲苯磺酰氯常用于形成磺酸盐混合酸酐,但该试剂具有高毒性、吸湿性、腐蚀性等缺点。利用磷酸类混合酸酐合成酰胺的方法中用到的试剂有:正丙磷酸酐和甲基乙基磷酸酐,该试剂价格较高且反应后会产生磷酸盐等副产物。
