An analysis of the PMR spectra of 2H, 6H-2, 6-dimethyl-4-amino-1,3,5-dithiazine, its acyl derivatives, and 2H, 3H, 6H-2, 6-dimethyl-4-amino-1,3,5-thiadiazine in various solvents and in the presence of Eu(FOD)3 [tris(1,1,1,2,2,3,3-heptafluoro-7,7-dimettyl-4,6-octanedionato)3 europium] confirms the structure assigned to it and makes it possible to prefer a cis orientation of the methyl substituents in the half-chair conformation.
