Abstract

Abstract: Several heterocyclic systems such as pyrano[2,3-c]pyrazole, pyrazolo[4,3:5,6] pyrano[2,3-d]pyrimidine and pyrazolo [4,3:5,6]pyrano-[3,2-e][1,2,4]triazolo[1,5-c]pyrimidine derivatives were obtained from the reaction of 1,3-diphenylpyrazole with 4-fluorobenzylidinemalo-nonitrile to give pyrano[2,3-c]pyrazole(1)as starting material.
