91. Molecular modeling (CAShe) of the free ligand 9b was used to establish the distance between the PhC(H)N and CH(OH) protons for each diastereomer. The PhC(H)N resonance showing the greatest relative NOE effect upon irradiation of the related CH(OH) proton was assigned as the SR diastereomer, because this isomer was calculated to have the shortest proton-proton distance (2.1 versus 2.3 Å for the SS diastereomer). The major isomer of 9a was also assigned as the SA diastereomers on the basis of the strong similarity of the NMR spectrum to that of the major isomer of 9b.
