Description

二吡咯甲烯-1-酮类化合物及其制备方法 技术领域
本发明专利属于药物化学领域,更具体地,本发明涉及一种二吡咯甲烯-1-酮类化合物及其制备方法。
背景技术
二吡咯甲烯-1-酮类化合物是一种重要的药物中间体,然而现有技术中,公开的二吡咯甲烯-1-酮类化合物种类不多,且对其化合物本身的用途鲜有研究,另外,已公开的具体二吡咯甲烯-1-酮类化合物合成方法复杂,例如,文献Bull.Chem.Pharm.Bull.Jp.1994,67(11),3088报道了该类化合物的合成方法,具体地,该文献以3-对甲苯磺酰基乙基-4-甲基-5-对甲苯磺酰基1,5-二氢-2H-2-吡咯酮为原料,在DBU和三丁基膦催化下与吡咯醛缩合,生成二吡咯甲烯-1-酮类。
Figure PCTCN2021073783-appb-000001
此外,5-对甲苯磺酰基-2-吡咯烷酮的合成是以对甲苯黄酰基乙烯为起始原料,经过加成,缩合,脱脂,成环,溴代,水解等步骤,得到产物。
Figure PCTCN2021073783-appb-000002
该路线反应路线长,一些步骤收率低,分离困难,需要柱层析方法分离,不适合工业化要求。合成过程要使用一些价格较高试剂如三丁基膦,三溴化三甲基苯胺等,增加了原料成本,另外需要使用一些污染大的试剂,如三氟乙酸,DBU等,以及一些毒性大,或易燃易爆试剂 如甲烷磺酰氯等,硝基甲烷等,限制了工业化生产。
因此,为解决现有技术存在的众多问题,有必要寻找更多的二吡咯甲烯-1-酮类化合物,挖掘二吡咯甲烯-1-酮类化合物的更多用途,研究更经济、安全、易于分离的二吡咯甲烯-1-酮类化合物的合成方法。
