Description
技术领域
本发明属于有机合成领域,尤其涉及一种苯并呋喃-3-甲酰胺化合物的制备方法。
背景技术
苯并呋喃-3-甲酰基是一种重要的结构骨架,广泛存在于天然产物和药物分子中。这些化合物具有抗抑郁、抗结核、抗糖尿病、抗肿瘤等生物活性(Curr.Med.Chem.2013,20,2820-2837;Eur.J.Med.Chem.2015,97,561-581;Eur.J.Med.Chem.2015,97,483-505;J.Med.Chem.2018,61,791-803)。
羰基化反应提供了一种直接、高效合成羰基化合物的重要方法(Chem.Rev.2019,119,2090-2127)。然而,基于羰基化反应合成苯并呋喃-3-甲酰胺化合物的报道较少,目前应用并不广泛,但其具有较大的应用潜力,有待深入研究。
基于此,我们发展了一种以2-炔基苯酚和硝基芳烃为起始原料,通过钯催化的羰基化反应高效、快速地合成苯并呋喃-3-甲酰胺化合物的方法。
发明内容
本发明提供了一种苯并呋喃-3-甲酰胺化合物的制备方法,该制备方法步骤简单,可以兼容多种官能团,反应适用性好。
一种苯并呋喃-3-甲酰胺化合物的制备方法,包括如下步骤:将钯催化剂、配体、碱、添加剂、水、2-炔基苯酚和硝基芳烃加入到有机溶剂中于80~100℃进行反应22~26小时,反应完全后,后处理得到所述的苯并呋喃-3-甲酰胺化合物;
所述的2-炔基苯酚的结构如式(II)所示:
所述的硝基芳烃的结构如式(III)所示:
所述的苯并呋喃-3-甲酰胺的结构如式(Ⅰ)所示:
R1为环丙基、取代或者未取代的苯基,所述苯基上的取代基选自C1~C6烷基、C1~C6烷氧基、卤素或者三氟甲基;R2为H、C1~C6烷基、C1~C6烷氧基、苯氧基或卤素。
具体反应式如下:
反应中可能首先经历了碘单质与2-炔基苯酚的碳碳三键配位。然后,2-炔基苯酚的羟基分子内进攻碳碳三键生成烯基碘化合物。其次,钯插入烯基碘形成烯基钯中间体,羰基钼放出的一氧化碳插入烯基钯中间体生成酰基钯中间体。最后,硝基芳烃依次经历硝基还原、亲核进攻酰基钯中间体、还原消除得到苯并呋喃-3-甲酰胺化合物。
本发明中,可选用的后处理过程包括:过滤,硅胶拌样,最后经过柱层析纯化得到相应的苯并呋喃-3-甲酰胺化合物,采用柱层析纯化为本领域常用的技术手段。
作为优选,R1为环丙基、取代或者未取代的苯基,所述苯基上的取代基选自甲氧基、甲基、正丁基、氟、溴或者三氟甲基;R2为H、Me、OMe、OPh、Cl、F或Br。
作为优选,所述的反应的时间为24小时,反应时间较短难以保证反应的完全。
作为优选,所述的有机溶剂为乙腈,此时,各种原料都能以较高的转化率转化成产物。
所述的有机溶剂的用量能将原料较好的溶解即可,0.3mmol的2-炔基苯酚使用的有机溶剂的量约为3mL。
作为优选,所述的钯催化剂为醋酸钯,在众多钯催化剂中反应效率较高。
所述的醋酸钯、三苯基膦和羰基钼的摩尔比为0.1:0.2:2.0;
作为进一步的优选,所述的苯并呋喃-3-甲酰胺化合物为式(I-1)-式(I-5)所示化合物中的一种:
上述制备方法中,所述的硝基芳烃、醋酸钯、三苯基膦和羰基钼一般采用市售产品,都能从市场上方便地得到,所述的2-炔基苯酚可由相应的2-碘苯酚和末端炔烃快速合成得到。
同现有技术相比,本发明的有益效果体现在:该制备方法易于操作,后处理简便;反应起始原料廉价易得,底物官能团容忍范围广,反应效率高,一步高效、快速合成出苯并呋喃-3-甲酰胺化合物,实用性较强。
