Abstract The multicomponent condensation of aldehydes, malononitrile derivatives, 1,3-dicarbonyl compounds of the carbo- and heterocyclic series, and alkyl halides has been studied. The transformation is initiated by the Knoevenagel reaction and leads to the formation of functionally substituted fused 2-amino-4H-pyrans. The structure of a few products was studied by X-ray diffraction (XRD) analysis
摘要 已经研究了醛、丙二腈衍生物、碳环和杂环系列的 1,3-二羰基化合物以及卤代烷的多组分缩合。该转化由 Knoevenagel 反应启动,并导致形成功能取代的稠合 2-amino-4 H -pyrans。通过 X 射线衍射 (XRD) 分析研究了一些产品的结构。
