    • 1H NMR assignments of the pro-R and pro-S hydrogens at C-23 of unlabeled 2, 3, and 4 (2, 3, 5). Stereochemical assignments of the 23-iodides are based upon analysis of NMR shieldings and coupling constants for the 23R epimer in conjunction with conformational analysis grounded in molecular modeling (2). Iodide and deuterium designated as 23R in the RS nomenclature system have the same stereochemical orientation as substituents at C-23.
