In this study, we report the synthesis of several novel dihydroisoxazole-, tetrahydroisoxazole- and dihydropyrazole-fused pyrido[2,3-b]quinolines, α-carbolines, and pyrido[2,3-c]coumarins, respectively, from simple precursors and by exploring intramolecular 1,3-dipolar cycloaddition reactions involving nitrile oxides, nitrones, and nitrile imines as 1,3-dipoles.
在这项研究中,我们分别报道了几种新型二氢异恶唑、四氢异恶唑和二氢吡唑并[2,3-b]喹啉、α-咔啉和吡啶并[2,3-c]香豆素的合成,它们分别来自简单的前体,并通过探索涉及腈氧化物、硝酮和腈亚胺作为 1,3-偶极子的分子内 1,3-偶极环加成反应。
