New 1-(1,2,3-triazol-4-yl)-benzimidazolone derivatives were obtained on pursuing research about new tricyclic derivatives of medicinal interest, bearing a 1,2,3-triazole ring fused with another heterocyclic ring. 1-[(5-Carboxamido)-1,2,3-triazol-4-yl]-benzimidazolone was prepared by four different chemical routes and it was unequivocally confirmed by spectroscopic methods. Its chemical behaviour, was
Four new triazolylbenzimidazolthione derivatives (2a-d), analogous to triazolylbenzimidazolone derivatives previously tested as activators of the BKCa potassium channels, were prepared and assayed without success. Some derivatives of a new tricyclic nitrogen heterocycle, 1,2,3-triazolo[1,5-a][1,3,5]benzo-triazepine, bearing a carboxamido group in the 3 position, other substituents in the 8 position
