2′-amino-2,5′-dioxo-5′,6′-dihydrospiro(indoline-3,4′-pyrano[3,2-c]quinoline)-3′-carbonitriles in good to excellent yields. The structures of all new products were proven using one- and two-dimensional NMR, IR, and mass spectral data, and in five cases X-ray structural analyses. The possible mechanism for the reaction is also discussed. Graphical abstract
摘要喹啉-2,4-二酮与吡啶中的2-(2-氧代-1,2-二氢吲哚-3-亚烷基)丙二腈反应生成2'-氨基-2,5'-二氧代-5',6'-二氢螺基(二氢吲哚-3,4'-吡喃并[3,2- c ]喹啉)-3'-腈的收率良好。使用一维和二维NMR,IR和质谱数据以及五种情况下的X射线结构分析证明了所有新产品的结构。还讨论了反应的可能机理。 图形概要
