| Abstract: | The reaction of cyclopentylidenecyanothiocetamide with cyanothioacetamide andN-methylmorpholine gaveN-methylmorpholinium 6-amino-3,5-dicyano-1,4-dihydropyridine-4-spirocyclopentane-2-thiolate, which was used in the syntheses of substituted 2-alkylthiodihydropyridines and pyrazolodihydropyridine.
