SUR UNE VOIE D'ACCES ORIGINALE AU SYSTEME PYRIDOPYRIMIDOPYRIMIDINIQUE

N,N-dimethyl amino uracile when reacting with N-dimethyl phosgeniminium chloride leads to a stable amide chloride which undergoes an heterocyclization reaction with pyridine to give a pyridopyrimidopyrimidine in a good yield.

Synthese et transformations de pyridopyrimidopyrimidines

A convenient one-step synthesis of a pyridopyrimidopyrimidine system by means of the chloride of 1,3-dimethyl-4-amino-5-(N,N-dimethyliminiumchloromethine)uracil and substituted pyridines is studied and the title compounds are described.
