Spectres RMN-13C DE β-Aminoalcools Derives DE L'Ephedrine ET De Leurs Oxazolidines

Abstract
The carbon-13 NMR spectra of β-aminoalcohols related to nor-and pseudonor-ephedrine (N-CH3; N-C2H5; N-iC3H7; N-tC4H9) and the series of the corresponding oxazolidines from formaldehyde and benzaldehyde were obtained and dicussed. The configuration of the 3-alkyl-2, 5-diphenyl-4-methyloxazolidines was established.
