Synthesis of some benzofuran-based pyrazoline, isoxazoline, pyrmidine, cyclohexenone and indazole derivatives

الملخص EN

In the present study benzofuran based chalcones 1(a, b) are synthesized by condensing aromatic aldehydes with 2-acetylbenzofuran in the presence suitable base.

These chalcones are very useful precursors for the synthesis of pyrazoline, isoxazoline, pyrmidine, cyclohexenone and indazole derivatives.

All these compounds are characterized by their melting points, FTIR and 1HMNR (for some of them) spectral data .
