CYCLIZATION OF NITRILES. XIII. 2,2-DIALKYL-4-AMINO-6-ARYL-5-CYANO-1,3-DITHIA-4-CYCLOHEXENES IN THE SYNTHESIS OF 4-ARYL-3-CYANOPYRIDINE-2(1H)-THIONES AND THEIR HETEROCYCLIC TRANSFORMATION PRODUCTS

2,2-Dialkyl-4-amino-6-aryl-5-cyano-1,3-dithia-4-cyclohexenes were obtained in the reaction of 2,2-propane- and 2,2-butanedithiols with arylidenemalononitrile.As a result of recyclization they formed substituted 4-aryl-3-cyanopyridine-2(1H)-thiones.The synthesized compounds were used in the synthesis of various 3-aminothienopyridines and some of their derivatives.
