CYCLIZATION OF NITRILES. XXXIV. TRANSFORMATION OF 4-ARYL-2,6-DIAMINO-3,5-DICYANO-4H-THIOPYRANS INTO SUBSTITUTED 4-ARYL-3-CYANO-2(1H)-PYRIDINETHIONES AND 2-AMINO-4-ARYL-7,7-DIMETHYL-5-OXO-3-CYANO-5,6,7,8-TETRAHYDRO-4H-BENZOPYRANS

The reaction of 2,6-diamino-3,5-dicyano-4H-thiopyrans with monocarbonyl and acyclic 1,3-dicarbonyl compounds leads to the elimination of malononitrile and the formation of substituted 4-aryl-3-cyano-2(1H)-pyridinethiones.The reaction with 1,3-cycloalkanediones leads to the elimination of cyanothioacetamide and the formation of 2-amino-4-aryl-3-cyano-4H-benzopyrans.
