A conformational study of 1,4-diacetyl-1,4-dihydro-6,7-dimethylquinoxaline is carried out by low temperature nmr in CD2Cl2.Important acetyl rotation induced shifts have been observed for the peri and ortho protons.These results, together with low temperature nOe experiments, permit the determination of the structures and conformations of four diacetyl derivatives of dihydropyrido as-triazines and of one diacetyl derivative of a dihydropyrido as-triazine.
