p-TsOH-promoted synthesis of (E)-6-phenyl-7-styryl-5,6-dihydrodibenzo[b,h][1,6]naphthyridines via cascade intramolecular aza-Michael addition/Friedlander condensation of 2′-aminochalcones in a SDS/H<sub>2</sub>O system

Brønsted acid-promoted cascade synthesis of novel (E)-6-phenyl-7-styryl-5,6-dihydrodibenzo[b,h][1,6]naphthyridines has been achieved via homodimerization of 2′-aminochalcones by employing sodium dodecylsulphate (SDS) as a surfactant in water. Besides water as an environmentally benign reaction medium, the reaction proceeds smoothly with high atom-economy under a sequential one-pot protocol.

A copper(II)-catalyzed cascade synthesis of 1H-pyrrolo[3,4-b]quinoline-1,3(2H)-diones has been achieved from readily available o-amino carbonyl compounds and maleimides. This one-potcascade strategy involves a copper-catalyzed aza-Michael addition followed by condensation and oxidation to deliver the target molecules. The protocol features a broad substrate scope and excellent functional group tolerance
铜 (II) 催化的 1 H-吡咯并 [3,4- b ] 喹啉-1,3(2 H )-二酮的级联合成已经从容易获得的邻氨基羰基化合物和马来酰亚胺中实现。这种单锅级联策略涉及铜催化的氮杂-迈克尔加成,然后进行缩合和氧化以传递目标分子。该协议具有广泛的底物范围和出色的官能团耐受性,并提供中等至良好 (44–88%) 产量的产品。
