Bis(enaminones) as Versatile Precursors for Novel Bis([1,2,4]triazolo[1,5‐ a ]pyrimidines) and Bis(2‐thioxo‐2,3‐dihydropyrido[2,3‐ d ]pyrimidin‐4(1 H )‐ones)

Novel bis([1,2,4]triazolo[1,5‐ a ]pyrimidines) and bis(2‐thioxo‐2,3‐dihydropyrido[2,3‐ d ]pyrimidin‐4(1 H )‐ones) were prepared utilizing bis(enaminones) as precursors. The structures of the prepared compounds were elucidated by several spectral tools as well as elemental analyses.
