The reaction of arylmethylenecyanothioacetamides with cyclohexanone or dimedone leads to the formation of 4-aryl-3-cyano-5,6,7,8-tetrahydro-2(1H)-quinolinethiones and 4-aryl-7,7-dimethyl-5-oxo-3-cyano-3,4,5,6,7,8-hexahydro-2(1H)-quinolinethiones, respectively.Upon heating in DMSO, these products undergo dehydrogenation to give 5,6,7,8-tetrahydro-2(1H)-quinolinethiones.These 2(1H)-quinolinethiones are smoothly alkylated at the sulfur atom by allyl bromide and phenacyl bromide.These transformations were used in the synthesis of substituted thienoquinolines and thiazoloquinolinium salts.

The reaction of arylmethylenecyanoacetamides with dimedone in the presence of bases proceeds with the formation of anti isomers of derivatives of ammonium 2-(2-thiocarbamoyl-2-cyanoethyl)-3-oxo-1-cyclohexen-1-olate.The ambident cyclization of these compou
