    • The major rotamer observed with one Mosher amide derived from one enantiomer of tropane is enantiomeric with the major rotamer derived from the opposite enantiomer of tropane with the opposite Mosher amide. Since these two compounds have identical NMR spectra, mixtures of Mosher amides can striaghtforwardly be assigned.

    • While the intermediate alcohol is not thermally stable, care must be taken to remove all of the ethanol before the elimination step. Typically, the crude oil was pumped under high vacuum (∼0.5 torr) for at least 30 min before the next step.
