The application of microwave irradiation shortened the reaction time to 10 min in comparison to ca. 48 h when 1,3‐dipolar cycloadditions were performed under standard conditions. All compounds were evaluated in vitro for inhibitory activity against a broad variety of DNA and RNA viruses. None of the compounds were antivirally active at subtoxic concentrations. Compound 17k exhibited moderate inhibitory
