synthesized via an auxiliary controlled diastereoselective aza-Claisen rearrangement. The stereodirecting unit is placed on an auxiliary derived from commercially available (S)-proline. After N-allylation. the obtained optically active allylamines were reacted with various N-protected glycyl fluorides to give the (2R)-C-allylglycyl amides in good yields. The diastereoselectivity of the asymmetric allylation
