Synthesis of 4,6-Disubstituted 2-Thioxo-1,2-dihydropyridine-3-carbonitriles by the Reaction of Acetylenic Ketones with Cyanothioacetamide

The reaction of acetylenic ketones with cyanothioacetamide in the presence of morpholine yields 4,6-disubstituted 2-thioxo-1,2-dihydropyridine-3-carbonitriles. Structure of the obtained compounds was proved using 2D NMR spectroscopy, as well as transformations into 3-aminothieno[2,3-b]pyridine-2-carboxamide derivatives.

The invention relates to novel pyrido[3',2':4,5]thieno[3,2-d]pyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=C-H, Y=S), thieno[2,3-d:4,5-d']dipyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=N, Y=S), in addition to pyrido[3',2':4,5]furo[3,2-d]pyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=C-H, Y=0) and furo[2,3-d:4,5-d']dipyrimidine-2,4(1 H,3H)-diones and -4(3H)-one (X=N, Y=O) of general formulae 1a and 1b. The invention also relates to a method for the production thereof, pharmaceutical preparations containing said compounds and/or tautomers thereof and physiologically compatible salts which can be produced therefrom and/or solvates thereof, in addition to the pharmaceutical use of said compounds, tautomers thereof, salts or solvates, as inhibitors of TNFa-release.

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.
