- 1,2,3-TRIAZOLOAZINES ET AUTRES HETEROCYCLES AZOTES DERIVES D'AZINE-CARBOXALDEHYDES
-
α-(N)-azine-carboxaldehydes are convenient precursors of 1,2,3-triazoloazines.Through oxidative cyclisation of the corresponding hydrazones we have prepared the new 1,2,3-triazolopyridazine and 1,2,3-triazolopyrazine.Unlike the other azaindolizines these compounds are degraded by electrophiles. attempts to prepare imidazopyrimidine or derivatives have been carried out either from 4-aminomethylpyrimidine or from ethyl 2-(4-pyrimidinyl)propionate.
