3-triazole-based pyridinamide ligands. The catalytic system effectively works for the coupling of N-substituted 2-halobenzamides with various active methylene compounds to form biologically relevant heterocyclic scaffolds in high to excellent yields. The consecutive path of the reaction including intermolecular C–C cross-coupling followed by intramolecularcyclization efficiently takes place at low catalytic loading

The glycosyl 1,2,3-triazoles are expediently accessible from readily available sugar-derived glycosyl azide by utilizing modular CuAAC “ClickChemistry”, and the resulting glycohybrid skeleton possesses efficient metal-coordinating centers that support a wide range of metal-mediated efficient catalysis in various imperative organic transformations. Here, we designed and developed pyridyl glycosyl triazoles
A base-free copper-assisted synthesis of <i>C</i><sub>2</sub>-symmetric spirotelluranes and biaryls based on divergent stoichiometry of Na<sub>2</sub>Te
methodology has been developed for the preparation of biologically important C2-symmetric spirodiaza, benzyloxy and benzoxytelluranes from 2-bromo-N-aryl benzamides, benzyl alcohols, and benzoic acids by using the tellurium dianion (Te2−) under base-free conditions. Furthermore, C–C coupled biaryl 1,1′-diamides have been prepared by using an excess of Na2Te under the same reaction conditions. The synthesized
