NH-1,2,3-triazole moieties are a part of the design of various biologically active compounds, pharmaceutical agents and functional materials. Unfortunately, the applications of this heterocycle are still underexplored due to the...
A one‐pot three‐component reaction of aldehydes, nitroalkanes and NaN3 for the synthesis of NH‐1,2,3‐triazoles has been developed. The reaction provides a safe, efficient and step‐economic approach for the synthesis of various NH‐1,2,3‐triazoles in good to excellent yields.
4-Aryl-NH-1,2,3-triazoles are valuable compounds in organic chemistry and pharmaceutical chemistry. In this paper, we describe a novel multicomponent reaction of aldehydes, nitroalkanes, and sodium azide for the synthesis of 4-aryl-NH-1,2,3-triazoles. In this transformation, it was found that both the slow addition of nitroalkane and the presence of NaHSO3/Na2SO3 are advantageous to promote the reaction

The synthesis of several 4-aryl-1,4-dihydrochromene-triazoles was achieved via a metal-free “one-pot” procedure using PEG400 as the sole solvent in an eco-friendly process. Using microwave irradiation, the triazole derivatives were obtained in good yields and short reaction times starting from readily accessible building blocks.
