Abstract
8-Aza-16-thiagona-12,17-diones have been obtained by the annelation of C(1)-unsubstituted 3,4-dihydroisoquinolines with 3-acylthiotetronic acids on refluxing in glacial acetic acid. The condensation of 1-methyl-3,4-dihydroisoquinoline with 3-acetylthiotetronic acid stopped at the salt formation stage. From the results of H/D isotopic exchange of 3,4-dihydroisoquinolinium 3-acetylthiotetronate it follows that a tautomeric equilibrium is established for the anion of 3-acetylthiotetronic acid, involving the protons of the acetyl group and the C(5) methylene group of the thiolactone ring in isotopic exchange.
