A series of new 1,2,3-triazole derivatives were designed and synthesised through Cu(I) catalysed 1,3-dipolar cycloaddition of alkynes and organic azides namely click reaction, under both conventional and microwave irradiation methods. Higher yields were achieved in lesser time under microwave irradiation method by using CuI as the catalyst. Herein, the two triazole moieties are linked through the O-alkoxy oxime linkage. All the synthesised molecular structures are elucidated by 1H-NMR, 13C-NMR, ...

Abstract A simple, efficient, eco-friendly and a green synthetic method has been developed for the synthesis of polysubstitutedpyrrolidinone derivatives via one-pot multi component reaction of aromatic aldehydes, aromatic amines with dimethyl but-2-ynedioate by using inexpensive non-toxic ionic liquid [bmim]BF4 under PEG-400 medium. The present methodology offers more environmental acceptability, higher yields with very shorter reaction time and recyclability of the ionic liquid.

A series of new 3-(5-methyl-1-aryl-1H-1,2,3-triazol-4-yl)-1-phenyl-1H-pyrazole-4-carbaldehydes 4(a–g) and their benzimidazole derivatives 6(a–g) were synthesized under both conventional and microwave irradiation methods. However, we successfully achieved good yields in shorter reaction times under microwave irradiation. All the synthesized scaffolds were characterized by 1H NMR, 13C NMR, IR and mass spectral analyses. The synthesized compounds have been evaluated as potential antiproliferative a...

Coumarin-based 1,4-disubstituted 1,2,3-triazole derivatives were synthesized using a highly efficient, eco-friendly protocol via a copper(I)-catalyzed click reaction between various substituted arylazides and terminal alkynes. The synthetic route was easy to access and gave excellent yields under microwave irradiation conditions compared to the conventional heating route. The structures of all the compounds were characterized by IR, 1H NMR, 13C NMR spectroscopy and mass spectrometry. All the syn...

Biaryl derivatives of spirofurochromanones have been synthesised from 4-bromophenyl derivatives of spirofurochromanones upon catalysis by Pd/C in water. Structures of the synthesised compounds are derived from IR, NMR and HRMS spectral data. The compounds have been tested for in vitro cytotoxicity supported by docking studies.
