The erythro- and threo-amphetamine-β-d diastereomers were synthesized and used for the unambiguous assignment of the diastereotopic benzylic protons and the measurement of vicinal 1H-1H coupling constants which were used to determine the distribution of rotamers around the central cα-cβ bond in the side chain.
