Intramolecular 1,3-dipolar cycloaddition reactions in the synthesis of complex annelated quinolines, α-carbolines and coumarins

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.

An efficient one-pot three-component reaction for the synthesis of novel functionalized pyrano[3,2-c]coumarins catalyzed by Na2CO3 in aqueous medium

An efficient green method for the synthesis of novel functionalized pyrano[3,2-c]coumarins from a one-pot three-component reaction of 4-hydroxycoumarins, dialkylacetylenedicarboxylates and alkyl acetonitriles catalyzed by Na2CO3 in aqueous medium was developed. The pure products were obtained in high yield from a simple work-up procedure.
