undergoes cycloaddition reactions with a range of substituted azides in the presence of copper salts to form 1,4-disubstituted triazoles 8–11 bearing the 4-hydroxycyclohexa-2,5-dien-1-one (quinol) pharmacophore; one example of an isomeric 1,5-disubstituted triazole 12 was formed from 5 and benzyl azide in the presence of a ruthenium catalyst. Compounds were screened for growth-inhibitory activity against
