Push-pull-Butadienes. II. Reactions of 2-Aryl-4,4-bis(methylthio)-1,3-butadiene-1,1-dicarbonitriles with Malononitrile and Ethyl Cyanoacetate

2-Aryl-4,4-bis(methylthio)-1,3-butadiene-1,1-dicarbonitriles 1 react with sodium salts of malononitrile or ethyl cyanoacetate 3 to give 4-aryl-2-methylthio-1,4-pentadiene-1,1,5,5-tetracarbonitriles and ethyl-4-aryl-1,5,5-tricyano-2-methylthio-1,4-pentadienecarboxylates 4, respectively.Also, arylethylidenemalononitriles 5 and bis(methylthio)methylenemalononitrile or ethyl bis(methylthio)methylenecyanoacetate 6 afford 4.Substituted dihydropyridines 8 are prepared by treating 4 with aromatic amines.Compounds 4d, e can be converted to 2-amino-6-aryl-4-methylthiobenzene-1,3-dicarbonitriles 11a, b.
