Synthesis and Biological Activities of 8,9-Disubstituted 4,5-Dihydro-2H--benzoxepinopyrazoles and Related Compounds

Condensation of 2,3,4,5-tetrahydro-1-benzoxepin-5-ones (2a-d) with different benzaldehydes affords the benzylidine derivatives (3a-d) which on epoxidation followed by treatment with hydrazine hydrate and arylhydrazines furnish the title benzoxepinopyrazol
