Synthesis of novel fused coumarine and naphtho[2,1-b]pyrano[3,2-e][1,2,4] triazolo[1,5-c]pyrimidine derivatives

New 14-(Aryl)-14H-naphto[2,1-b]pyrano[3,2-e][1,2,4]triazolo[1,5-c] pyrimidine-2-Acetonitriles have been prepared. The chemical behaviour of these compounds was studied towards Knoevenagel condensation with salicylaldelyde derivatives, thus, a series of 2-
