A metal-free approach has been developed for the synthesis of benzo[c]isoxazole (anthranils) containing 1,2,3-triazoles. The reaction proceeded efficiently through a [3 + 2] azide-alkyne cycloaddition, SNAr azidation and denitrogenative cyclization sequence. The metal-free protocol enabled effective construction of one N-O and three C-N bonds in one pot. In addition, the synthetic utility of the current methodology was further demonstrated by late stage modification of the obtained products.

We herein describe an efficient copper-catalyzed three-component domino protocol used to prepare 2,1-benzoisoxazole-containing 1,2,3-triazoles from commercially available o-bromoacetophenones, aldehydes, and sodium azide. This domino process involves Aldol condensation, copper-catalyzed azide-chalcone oxidative cyclization, 1,2,3-triazole-assisted azidation, and denitrogenative cyclization sequences. The formed compounds could be considered as benzo[c]isoxazole-functionalized combretastatin A-4 triazole analogues, which might be potential applications in the discovery of a new anticarcinogen.
