The copper-catalyzed cascade reaction comprising the condensation/α-arylation between 2-halobenzaldehydes and α-amino acid esters provides a straightforward methodology for the efficient synthesis of alkyl 2H-isoindole-1-carboxylates.

An operationally simple and efficient cascade strategy has been developed to access substituted isoindolo[2,1-a]quinoxalines through a one-step copper-catalyzedC–Ncoupling reaction between substituted 2H-isoindole-1-carbaldehydes and substituted 2-halophenylamines. Another straightforward procedure is described to prepare substituted isoindolo[2,1-a]quinoxalin-6(5H)-ones, which involved the transformation
