Briel, Detlef
, p. 345 - 348 (2007/10/02)
The (thioaroylamido)acrylonitriles 2, obtained by reaction of 1,2,4-dithiazolium salts 1 with ethyl cyanacetate, undergo ring tranformation reactions by reaction with ammonium acetate, primary and secondary amines and form the pyrimidines 7-9.A possible mechanism for these reactions is discussed.
