Synthesis of N-Methylmorpholinium 6-Amino-4-aryl-3,5-di-cyano-1,4-dihydropyridine-2-thiolates by the Michael Reaction

N-Methylmorpholinium 6-amino-4-aryl-3,5-dicyano-4-methyl-1,4-dihydropyridine-2-thiolates substituted in position 4 are obtained by the reaction of 2-substituted 1,1-dicyano-2-methylethylenes with cyanothioacetamide in the presence of N-methylmorpholine. Dimedone reacts with isopropylidenemalononitrile in the presence of catalytic amounts of N-methylmorpholine to afford 2-amino-5-oxo-4,4,7,7-tetramethyl-3-cyano-5,6,7,8-tetrahydro-4H-benzo[b]pyran.
