Multicomponent reactions of primary 1,2- and 1,3-diamines with carbonyl compounds and isocyanides resulting in the formation of diverse 2-amino-1,4-diazaheterocycles are described. Lewis acids (LAs) promote the reactions effectively, and chlorotrimethylsilane (TMSCl) has been found to be a promoter of choice. The scope and limitations of the reactions with regard to each of the components are evaluated
描述了伯 1,2-和 1,3-二胺与羰基化合物和异氰化物的多组分反应,导致形成不同的 2-氨基-1,4-二氮杂环。路易斯酸 (LA) 可有效促进反应,并且已发现三甲基氯硅烷 (TMSCl) 是首选的促进剂。评估和讨论了与每个组分有关的反应的范围和限制。已详细阐述了合成杂环的 IMCR 后修饰。
