Abstract: | NMR spectra of norfluorocurarine and seven of its derivatives were studied. The NMR spectral parameters were related to stereochemical features using molecular modeling by the semi-empirical AM1 approximation. The resulting steric characteristics of the molecules in solution agreed well with x-ray structure data. The only difference from the x-ray structure data was the ability of several substituents to rotate. |
