The reduction by LAH of α-asymmetric-β-amino propiophenones is stereospecific and affords the erythro amino-alcohols as predominant diastereomers. The configurations of these amino-alcohols have been assigned by correlation of IR and NMR spectra, from which their preferred conformations have been also deduced.
