three-component condensation of 1H-pyrrole-2,3-diones, malononitrile, and 4-hydroxyquinolin-2(1H)-ones was developed. The reaction can lead to the formation of spiro[pyrano[3,2-c]quinoline-4,3′-pyrrole] derivatives or the substituted 1,5-dihydropyrrole-2-ones depending on the substituents of 1H-pyrrole-2,3-diones and reaction conditions.
开发了一种有效的区域发散性三组分缩合的1 H-吡咯-2,3-二酮,丙二腈和4-羟基喹啉-2(1 H)-ones。根据1 H-吡咯-的取代基,该反应可导致螺[吡喃并[3,2 - c ]喹啉-4,3'-吡咯]衍生物或取代的1,5-二氢吡咯-2-酮的形成。2,3-二酮和反应条件。
