β-Hydroxy-DL-norvaline (HyNva) was successfully separated into its diastereoisomers by fractional crystallization from 2-propanol as p-toluenesulfonic acid (TsOH) salts.The two racemic diastereoisomers were resolved into four stereoisomers by Vogler's method, using diastereisomers of the N-benzyloxycarbonyl DL-amino acid and L-tyrosine hydrazide.
