A series of pyridines, pyrimidinones, oxazinones and their derivatives were synthesized as antimicrobial agents using citrazinic acid (2,6-dihydroxyisonicotinic acid) as a starting material. α,β-Unsaturated ketones 3a-c were condensed with cyanothio-acetamide in the presence of ammonium acetate to give 2-cyanopyridinethiones 4a-c

Although brominated bipyridines and terpyridines are highly desirable synthetic building blocks for both ligand design and macro- or supramolecular applications, few such synthetic precursors have been reported that include much-needed solubilizing groups. Reported here is an inexpensive route to 2,6-dibromo-4-(hexoxymethyl)pyridine
