Abstract

By the interaction of a 4-R-cyclohexylidenecyanoacetic ester with cyanothio(seleno)acetainide, 6-oxo-3, 5dicyano-1,4,5,6-tetrahydrospiro(4′-R-cyclohexane-1',4-pyridine)-2-thiols and -selenols have been obtained; these have also been synthesized from a cyclohexytidenecyanothioacetamide and cyanoacetic ester. These thiols and selenols have been used to prepare the corresponding disulfides, diselenides, and spiro systems, including the fragments alkylthio(seleno)tetrahydropyridine, thieno[2, 3-b]pyridine, and 2,3-dihydrothiazolopyridine.
