Cytostatics. 19. Configurative assignment of diastereomer N,N'-dialkyl-alpha ,alpha '-diphenylethylenediamines by nuclear resonance spectroscopy

Schönenberger, R. ; Sunkel, C. ; Schönenberger, Helmut



Abstract

The assignment of the configuration of o-R1C6H4CH(NHR)CH(NHR)C6H4R1-o (I; R = H, Bu, or Me2CHCH2; R1 = H or Cl) by PMR used the different chem. shifts of the ethylene protons (alpha -H) and arom. protons. The meso form exhibited a paramagnetic shift for the arom. protons and a diamagnetic shift for alpha -H compared to the racemic form. Corresponding differences were obsd. in the spectra of the ...
