The first and facile synthesis of N,N′-dialkylated 2,6,9-triazabicyclo[3.3.1]nonadienes was achieved by the [4 + 4] self-condensation of β-formyl-β-nitroenamine in the presence of ammonium acetate. The 2,6- A nd 2,9-dialkylated products were found to be interconvertible when dissolved in a solvent. This isomerization proceeds through intramolecular ring transformation via a common intermediate under equilibrium. This journal is

During the reaction of 6-nitroazolopyrimidines with dialkylanilines the products from addition at the carbon atom, i.e., 6-nitro-7-p-dialkylaminophenyl-4,7-dihydroazolopyrimidines are formed.The reaction with aniline and its derivatives leads to destruction of the pyrimidine ring as a result of N-addition of the arylamine.
