The novel tricyclic ring systems 14 can be prepared by reaction of thienopyrazoles 5 with 1, 3-dielectrophiles, such as acetylacetone, dibenzoylmethane or 1, 2, 4-dithiazole 8. An other synthetic route for the preparation of the tricyclic systems, based on the pyrazoloazines 13, was investigated. The compounds 5 and 14 were tested for antiulcer activity.
