A library of twenty five amide linked 1,4-disubstituted 1,2,3-triazoles have been prepared through a facile expeditious synthetic protocol involving Cu(I) mediated cyclization of N-(2-methylbut-3-yn-2-yl)aromatic amides and in situ generated 2-azido-N-substituted propanamides. Structures of newly synthesized compounds (5a–5y) were confirmed by analytical techniques, such as FTIR, 1H NMR, 13C NMR, and HRMS. In vitro antifungal activity was also examined against two fungal strains Candida albicans and Aspergillus niger by serial dilution method. The compounds 5 m and 5w exhibited appreciable potent activity.

The synthesis of substituted dihydrooxazoles by the CuI-catalyzed cycloisomerization of terminal propargyl amides is reported. The reaction has been shown to have good substrate scope and experiments to delineate the mechanism have been performed. Substrates containing a benzylic methylene were oxidized to the ketone under the reaction conditions.
