β-D-C-Allosyl-(R)-alanine 12 and β-D-C-altrosyl-(R)-alanine lactone 15 were synthesized from the common intermediate 7 in just a few steps.The β-C-glycosyloxazolone 7 was obtained in two steps from the protected D-glucal 4 by a sequential coupling with N-benzoylalanine followed by a Claisen rearrangement.
