A new chemoselective approach to synthesize a series of benzoimidazole 2a-c, 3, 4a, b and benzoxazol-2-thiol derivatives 5a-c, 6, 7a,b. Benzoxazol-2-thiol derivatives under action of N-nucleophiles, by using this methodology, two series of heterocyclic systems were synthesized. 7-Chloro-2-methyl/or aryl-benzo-[4,5]imidazo[1,2,4] thiadiazole derivatives 8,9 and 10a-c were prepared via cyclocondensation and condensation elimination reaction.
