Abstract
The activity of three copper(I)-based catalytic systems in the preparation of various 1,2,3-triazolyl-carbanucleosides via the Huisgen azide-alkyne 1,3-dipolar cycloaddition is presented. The influence of the alkyne substituent, solvent, and heating mode were studied. The preparation of [1,2-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene]bromocopper [(IMes)CuBr] is discussed.
