Hitherto unknown group of tricyclic fused pyrazolines have been synthesized by the reaction of 3-arylidenechromano-nes and 3-arylidene-1-thiochromanones with (4-carboxyphenyl)hydrazine in hot anhydrous pyridine solution. Structures of all new compounds have been elucidated by microanalyses, IR, 1H, 13C NMR and mass spectrometric measurements.
