SPECTRES RMN-1H ET -13C DE PHENYL-1-PROPANEDIAMINES-1,2 DERIVES DE L'EPHEDRINE ET DE LEURS IMIDAZOLIDINES

Tytgat, D.,Gelbcke, M.

, p. 243 - 256 (2007/10/02)

A series of N1-methyl-1-phenyl-1,2-propanediamines substituted at the nitrogen (N2) by alkyl groups (CH3, C2H5, i-C3H7, t-C4H9) and the corresponding imidazolidines from formaldehyde have been synthesized.The study of their 1H- and 13C-NMR spectra allowed the differentiation of the diastereoisomers in these two series.
