The polyfunctionalized title triazolyl 1,3-diketones have been prepared by the addition-cyclization reaction of sodium azide to 1,5-diaryl-4-pentyne-1,3-diones, in the first instance, in good yields.These intermediate triazoles can readily be cyclodehydrated to the corresponding 3,6-diaryl-4H-pyrrolo<1,2-c><1,2,3>triazol-4-one derivatives.This cyclodehydration furnishes a new method of synthesis of a new class of pyrrolo<1,2-c><1,2,3>triazoles.The structures of the above compounds were confirmed from their spectral characteristics.
