Feature Article

Copper(i)-catalyzed azide–alkyne cycloaddition (CuAAC) provides an efficient synthesis of 1,4-disubstituted 1,2,3-triazoles. This feature article highlights the recent progress on the regisoselective synthesis of multisubstituted 1,2,3-triazoles, which current click reaction (CuAAC) is unable to do.

Regioselective synthesis of some amide?ether-linked 1,4-disubstituted 1,2,3-triazoles was realized via the copper(I)-catalyzed click reaction of 1-(prop-2-ynyloxy)naphthalene, 2-(prop-2-ynyloxy)naphthalene and 1,4-bis-(prop-2-ynyloxy)benzene with 2-azido-N-substituted acetamides. The synthesized compounds were characterized by spectral techniques viz. FT-IR, 1H- -NMR, 13C-NMR, HRMS and evaluated for their in vitro antimicrobial activity against Bacillus subtilis, Staphylococcus aureus (Gram-positive bacteria), Pseudomonas aeruginosa, Escherichia coli (Gram-negative bacteria), Candida albicans and Aspergillus brasiliensis (fungi). Among the synthesized 1,4-disubstituted 1,2,3-triazoles, compound 13d displayed excellent antibacterial potential, while, compounds 7d and 13d appeared as potent fungicidal agents against the tested microbial strains. The docking simulation of the broad spectrum microbicidal disubstituted 1,2,3-triazole 13d into the active site of E. coli type II topoisomerase, DNA gyrase B enzyme was also investigated.

Monometallic Nanoparticles

Compared to monometallic nanoparticles, bimetallic nanoparticles have attracted wide attention due to their physical properties, excellent catalytic activity, high regioselectivity, selectivity, and stability. Here, we have first synthesized 10 different kinds of graphene quantum dot–stabilized Cu-based bimetallic nanoparticles (including CoCu, NiCu, RuCu, RhCu, PdCu, AgCu, IrCu, AuCu, FeCu, and PtCu) and compared their catalytic activities in a CuAAC click reaction. Among them, RhCu provides the highest yield of the desired product in the click reaction (77%). The catalytic activity of these MCu in the click reaction is in the order: RhCu > PdCu > AuCu > CoCu > PtCu > AgCu > NiCu > CuNP > RuCu > FeCu > IrCu.

Low Molecular Weight Organogelators

A facile regioselective synthesis of bis-triazologlycolipids, a class of organogelators, has been accomplished by “Click reaction”. The morphology and self-assembly of the gelators were examined by FESEM and HRTEM analysis.
