assembly of novel, biologically relevant dihydropyrrolo[1,2-a]quinoxalines-amidines is herein presented. Starting from 1-(2-aminophenyl)pyrroles, aldehydes, and isonitriles, the target heterocyclic scaffold is assembled in a one-pot, operationally friendly process. With three points of diversity and formation of three chemical bonds in one step, this strategy proves to be very general. Novel, mild methodology
本文提出了一种基于异氰化物的多组分反应(IMCR),用于快速组装新颖的、生物学相关的二氢吡咯并[1,2- a ]喹喔啉-脒。从 1-(2-氨基苯基)吡咯、醛和异腈开始,目标杂环支架通过一锅、操作友好的过程组装而成。由于具有三个多样性点并一步形成三个化学键,这一策略被证明是非常通用的。还介绍了从仲胺苯胺和异腈生成脒的新颖、温和的方法。
