Various C-aryldeoxyribosides were conveniently prepared from the C-alkynyldeoxyribosides in good yields. The underlying strategy is based on [2+2+2]-cyclotrimerization catalyzed by rhodium and ruthenium complexes. The reaction could be carried out under ambient conditions or microwave irradiation depending on the degree of substitution.
