Reported here is an efficient procedure for enantio- and diastereoselectivesynthesis of pure β-amino acids that display a tert-hydroxyl functionality in the α-position. Key steps include a catalytic asymmetric aldol reaction and a modified Curtius rearrangement to form oxazolidinone intermediates, which are chemoselectively opened to furnish N-protected α-hydroxy-α-methyl-β-amino acids. A modified
