CuO-Promoted Construction of N-2-Aryl-Substituted-1,2,3-Triazoles via Azide-Chalcone Oxidative Cycloaddition and Post-Triazole Arylation
摘要:
An efficient one-pot three-component stepwise approach for the synthesis of N-2-aryl-substituted-1,2,3-triazoles has been developed. By using this azide-chalcone oxidative cycloaddition and post-triazole arylation, a series of N-2-aryl-substituted-1,2,3-triazoles are readily prepared under mild conditions in excellent yields and high regioselectivity. Both the catalyst and substrates are readily available.
A binuclear Cu(I) complex containing a N′,N′-bis(1H-indol-3-yl)methylene}oxalohydrazide (H2bioh) ligand has been synthesized and characterized. The molecular structures of the synthesized compounds have been determined by single crystal X-ray diffraction. The crystal structures are stabilized by inter- and intra-molecular π–π stacking and C–H⋯π interactions. The Cu(I)-complex has successfully been
