Abstract

Thienopyrimidines (2, 3, 4) and triazolo- thienopyrimidines (5a-c) were prepared from the precursor 2-amino-5, 5-dimethyl-7-oxo-4, 5, 6, 7-tetrahydro-1-benzothiophene-3-carbonitrile (1) by employing the microwave irradiation technique. The precursor 2-amino-3-cyanothiophene analogue (1) was synthesized by employing the well-known Gewald reaction. In the present work it has been found that the microwave supported syntheses is more efficient than the classical heating method. The structures of all the compounds were ascertained by spectral and analytical data. The compounds have showed promising antibacterial and antifungal activities
