The active methylene group in acetonitriles of the type CH2YZ (Y=CN, Z=R or Ar) (II) undergoes condensation readily with pyridinium salts (Ia-d) to yield 4-substituted 1,4-dihydropyridines.The active methylene group present in the thiazolidone (XIV) and oxazolone (XV) rings also react with 1 to give the corresponding 1,4-dihydro(thiazolono)-pyridines.
