various benzopyranopyrazole derivatives namely [1,9-b]dihydro-3a- nitro-4-phenyl[1]benzopyrano[3,4-c]pyrazolines(4a-h), 4-phenyl[1]benzopyrano [3,4-c]pyrazoles (5a-h) and [1,9-b]dihydro-1-methyl-3a-nitro-4-phenyl[1]benzopyrano[3,4-c]pyrazolines (6a-h) respectively. The regio and stereochemical outcome of these cycloadditions are discussed. The benzopyranopyrazole derivatives 4a-h and 6-ah were tested
