- NOVEL INTRAMOLECULAR DIELS-ALDER REACTIONS WITH ALKYNYLTHIO DERIVATIVES OF 1,2,4-TRIAZINES. NEW ROUTES TO THIENOPYRIDINES AND THIENOPYRIDINES
-
S-Alkylation of 1,2,4-triazine-6-thiones with 4-iodobutyne, followed by oxidation to the sulfoxide and intramolecular cycloaddition (at room temperature), gives 2,3-dihydrothienopyridines, which are readily dehydrated with acetic anhydride to thien
