N-Phenyl-N-thiocarbamoyl-alpha- and beta-methyl-beta-alanines were converted into a series of 1,3-thiazole derivatives by treatment with chloroacetaldehyde and haloketones. The reaction of N-phenyl-N-thiocarbamoyl-beta-alanines and N-carbamoyl-N-phenyl-beta-alanines with 2,3-dichloro-1,4-naphthoquinone and 2,3-dichloroquinoxaline provided naphthoquinone- and quinoxaline-fused thiazoles and oxazoles, respectively. A number of the synthesized compounds exhibited good antibacterial activity against Staphylococcus aureus and Salmonella enteritidis with MIC and MBC values (62.5 and 125 mu g/mL, respectively) which are the same or even lower than those for the antibiotic oxytetracycline.
