Abstract
:
1-Phenyl-3-trifluoromethyl-2-pyrazolin-5-one 1 on heating with aromatic aldehydes at 160-70 degrees C affords the corresponding 4-arylidene-2-pyrazolin-5-ones 3, while 3-amino-1-phenyl-2pyrazolin-5-one 2 on heating with aldehydes gives pyrazolopyranopyrazole derivatives 4 with high yields. These new products have been characterized by spectroscopic techniques and elemental analysis.
