Article abstract of DOI:10.1016/S0040-4020(01)87461-5

The observed chemical shift non-equivalence of the diastereotopic methylene protons in primary camphanamides is rationalized in terms of chirality independent, differential shielding of H_S by the amide carbonyl, as deduced by nmr solution, X-ra
