The invention relates to methods for producing chalcone (1,3-diphenylprop-2-en-1 -one) derivatives that have multiple substitutions on a phenyl ring. Intermediate chalcone derivatives are modified by Phase Transfer Catalysis (PTC) for introducing a substituted alkyl group that is provided by a sulfonic acid derivative on a phenyl ring already containing substituent groups on one or two carbon atoms adjacent to the carbon atom where a substituent group is being introduced. The methods of the invention allow producing efficiently, by either S-alkylation or O- alkylation, chalcones derivatives that are characterized for their biological activities that are intermediate compounds for producing molecules having such activities, or that can be used for generating libraries of compounds to be screened by means of in vitro and/or in vivo assays and establishing structure-activity relationships.
该发明涉及一种生产苯并二氮杂环(1,3-二苯基丙-2-烯-1-酮)衍生物的方法,该衍生物在苯环上具有多个取代基。通过相转移催化(PTC)修改中间苯并二氮杂环衍生物,以引入由苯环上的磺酸衍生物提供的取代烷基基团,该苯环已含有相邻碳原子上的取代基团,其中一个或两个碳原子上的取代基团与引入的取代基团相邻。该发明的方法允许通过S-烷基化或O-烷基化高效地生产苯并二氮杂环衍生物,这些衍生物以其生物活性而闻名,是用于生产具有这些活性的分子的中间化合物,或可用于生成化合物库,通过体外和/或体内试验筛选,并建立结构活性关系。
