New Synthetic Routes to 1,3,4-Thiadiazole Derivatives

On the nucleophilic derivatization of 4,7-dibromo-[1,2,5]thiadiazolo[3,4-c]pyridine: basis for biologically interesting species and building blocks for organic materials

Eleven new thiadiazolopyridine-derived building blocks were synthesized through a selective S_NAr reaction and the key steps of their reaction mechanism and spectroscopic properties were studied.

Pyrimidinethione as a building block in heterocyclic synthesis: synthesis of pyrano[2,3-d]pyrimidine, chromeno[2,3-d]pyrimidine, pyrido[3′,2′:5,6]pyrano[2,3-b]pyridine, and pyrimido[5′,4′:5,6]pyrano[2,3-d]pyrimidine derivatives

New heterocyclic compounds with expected biological activity have been prepared by reactions of 6-phenyl-2-thioxo-2,3-dihydropyrimidine-4(5
