Stereoselective Intramolecular Azide 1,3-Dipolar Cycloaddition
Ethyl (E)-7-azido-6-[bis(tert-butoxycarbonyl)amino]-2-heptenoate undergoes a stereoselective intramolecular azide 1,3-dipolar cycloaddition leading to a stable triazoline. The configuration and the conformation of the triazoline obtained were determined by spectroscopic data and confirmed by molecular mechanics calculations.

Synthesis of new triazole-based trifluoromethyl scaffolds
Trifluoromethyl propargylamines react with various azide derivatives to afford 1,4-disubstituted 1,2,3-triazoles through a Huisgen 1,3-dipolar cycloaddition. The reaction is catalyzed by a Cu(I) species in acetonitrile, and the corresponding products are
