Description

一种羟基取代色满类化合物的合成
技术领域
本发明具体涉及一种制备羟基取代的色满类化合物的合成方法,属于有机化合物工艺应用技术领域。
背景技术
色满类化合物是一类非常重要医药化工中间体,具有非常高的应用价值。在很多药物和生物活性分子,如ormeloxifene,NSC 381582, (+)-hematoxylin, Myristinin A,等,都具有色满的骨架,如下所示:
合成色满类化合物的传统方法主要是通过金属催化的环加成反应来完成。但是此方法中,反应原料和催化剂都比较昂贵,且重金属的使用会对环境造成较大的污染,使此方法的应用受到制约。
发明内容
本发明克服现有技术的以上缺陷,首次创新地提出了一种绿色环保,简单高效制备含有羟基取代的色满类化合物的新方法,通过使用路易斯碱为催化剂,可以高效地实现反应的转化。如以上式(I)所示,本发明利用以对位醌的亚甲基化合物和羰基化合物为反应原料,以路易斯碱为催化剂,在反应溶剂中进行反应,合成含有羟基取代的色满类化合物化合物。
本发明中,R、R1和R2是烷基、芳香基或取代的芳环和杂环、各类侧链。
本发明中,所述起始原料对位醌的亚甲基化合物和羰基化合物的用量比例为1:2。优选地,两者用量比例为1:1.2。
本发明中,所述催化剂是DBU;所述催化剂的用量为1-100%。所述催化剂的用量为原料对亚甲基醌的1-100mol%。优选地,所述催化剂用量为5 mol%。
本发明中,所述反应溶剂是甲苯、氯仿、四氢呋喃、DMA、1,2-二氯乙烷、THF或乙腈。所述反应溶剂包括但不局限于以上,还可以是氯苯、1,4-二氧六环、DMF,DMSO。
本发明中,所述合成反应是在20-80℃温度下进行。优选地,是在25℃温度下进行反应。
具体地,本发明合成反应是在反应瓶A中,将对亚甲基醌(底物1,X mmol) 和羰基化合物(底物2,Y mmol)溶解在Z mL反应溶剂中,室温下,加入DBU(W mmol)。反应在20-80℃下反应48个小时。用TLC检测反应进程。反应完毕后,直接加硅胶,旋干柱层析,分离得到目标产物3。
本发明合成反应的优点包括:本发明合成方法所使用的各原料非常简单,简单易得,来源广泛,并且性能非常稳定,不需要特殊保存条件。本发明所用的各种催化剂也都是常用的商品化试剂,非常稳定。合成色满类化合物的传统的方法通过金属催化的环加成反应来完成。但是此方法中,反应原料和催化剂都比较昂贵,且重金属的使用会对环境造成较大的污染,使此方法的应用受到制约。本发明以简单易得的对亚甲基醌和羰基化合物为反应原料,在路易斯碱作用下,反应得到羟基取代的色满类化合物。反应操作比较简单,反应条件温和,产率较高,适合大规模工业化生产。本发明合成的羟基取代的色满类化合物是很多天然产物和活性药物分子的核心骨架,本发明创新设计的反应路线为合成这类化合物提供了一个广泛适用的制备方法。
