Synthesis of New Fused Hetecrocyclic Compounds of Benzpyrid‐4‐One Derivatives and Their Some Biological Activity

A series of fused pyrazolino‐, Isoxazolino‐, Pyrimidino‐, Pyrimidinothino‐, thiazolidinones and β‐lactam incorporating benzpyrid‐4‐one derivatives have been synthesized by different methods of chemical reaction. The prepared compounds were established by universals and modern methods of physical and chemical confirmation.
