Substituted thienopyridines (VIII-XII) were prepared by ring closure of the corresponding S-alkylated derivatives (II-VI).Thienopyridine-2-carbohydrazide XIII was interacted with some reagents afforded the expected pyridothienopyrimidines (XIV-XVI).Also, the carboazide XVII undergo Curtius rearrangement giving imidazolothienopyridine (XVIII).The carboxamide derivatives (X-XII) interacted with CS2 giving pyridothienopyrimidines (XX-XXII), while interaction with nitrous acid, pyridothienotriazines (XXIII-XXV) were produced.
