By the interaction of a 4-R-cyclohe.xylidenecyanoacetic 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-bjpyridine, and 2, 3-dihydrothiazolopyridine.
