Abstract

Hitherto unreported [1,2,3]-triazolyl coumarin and quinolone derivatives in good to excellent yields have been expediently synthesized from 6- and 7-azidocoumarin and 6-azidoquinolone by copper (I) catalyzed 1,3-dipolar cycloaddition. Azidocoumarins and azidoquinolones were in turn prepared efficiently from the corresponding amines. Fluorescence studies of the newly synthesized [1,2,3]- triazolyl coumarin and quinolone derivatives are also described.
