    • note
    • As previously reported in Ref. 8a, the relative stereochemistry of the rearrangement products was determined by conversion of the allylic trichloroamides into the corresponding oxazolidin-2-ones. Using NOE experiments then allowed assignment of the major diastereomer. More recently (Ref. 10a), the conversion of the allylic amides into known β-hydroxy-α-amino acids has further confirmed this original assignment.

    • 1H NMR spectra produced from rearrangement of the carbon analogue and allylic amide 10 allowed confirmation of diastereomer b as the major product from these reactions.
