Intramolecular Diels-Alder reactions of 6-(alkynylthio)-1,2,4-triazines are shown to give 2,3-dihydrothienopyridines and 3,4-dihydro-2H-thiopyranopyridines. 1-Oxo-2,3-dihydrothienopyridines synthesized in this fashion from the corresp
NOVEL INTRAMOLECULAR DIELS-ALDER REACTIONS WITH ALKYNYLTHIO DERIVATIVES OF 1,2,4-TRIAZINES. NEW ROUTES TO THIENOPYRIDINES AND THIENOPYRIDINES
Taylor, Edward C.,Macor, John E.
, p. 2419 - 2422 (1985)
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
