MISE EN EVIDENCE PAR RMN-(1)H ET -(13)C D'ISOMERISME Z/E ET D'EQUILIBRE CONFORMATIONNEL SUR UNE SERIE DE DERIVES MONO- ET DIACETYLES DE 2-ALKYLAMINO-1-PHENYLPROPAN-1-OLS

(1)H- and (13)C NMR studies of mono- and diacetylated-erythro- and threo-2-alkylamino-1-phenylpropan-1-ols, C6H5CHOHCHNHRCH3 (R = H, CH3, C2H5 AND i-C3H7) show that the series exhibit Z/E isomerism about the C-N amide bond.The Z/E ratio increases in the monoacetylated series CH3 1-C2 and N-C2 bonds.In the Z configuration, the conformer Z-s-syn where the proton H-2 is syn with the N-alkyl substituent predominates.
