SYNTHESIS AND ANTIBACTERIAL PROPERTIES OF NEW DITHIENYL CONTAINING PYRAN, PYRANO[2,3-b] PYRIDINE, PYRANO[2,3-d]PYRIMIDINE AND PYRIDINE DERIVATIVES

Abstract Some new pyran 3,8; pyrano[2,3-b]pyridine 4; pyrano[2,3-d] pyrimidine 5,6,7 and 9; pyridine 10–14 derivatives have been prepared. The structure of all the new compounds have been established on the basis of elemental analyses and spectroscopic data. All the synthesized compounds have been screened for their antibacterial activity. Pyranopyrimidinethione 7 and pyridinethione 10 exhibited a good antibacterial activity compared with the standard antibiotic Gentamycin.
