Synthesis and Antimicrobial Evaluation of Some New Heterocyclic Compounds from Thienopyridine and Pyrazolopyridine Derivatives

Synthesis and antimicrobial activities of a variety of functionalized pyrido[3`,2`:4,5]thieno[3,2-d]pyrimidine, pyrazolo[3`,2`:4,5]thieno[2,3-b]pyridin-3-one and thieno[2,3-b]pyridine derivatives are illustrated. Structures of the newly synthesized compounds were elucidated based on their elemental analyses, spectral data and alternative synthesis whenever possible.
