In the search for new therapeutic agents against microbial infections, two novel series of monocyclic and tricyclic 5-(phenylazo)thiophene systems were synthesized based on 3-amino-2-thioxopyrimidinone and 2-cyanoacetamidothiophene derivatives 4 and 6. Functionalization of the pyrimidine ring in precursor 4 resulted in the formation of the target tricyclic condensed thiophenes 7, 12, and 13a, b, by
