Résumé : A series of β-aminothiosulfonic acids related to nor- and pseudonorthioephedrine (N-CH3; N-C2H5; N-iC3H7 acid N-t C4H9) has been synthesized. The study of their 1H-NMR and 13 C-NMR spectra allowed the differentiation of them. The substitution by a tertiary butyl group give rise to important modifications and produce an unexpected γ deshielding effect. © 1983.
