A concise synthesis of α-amino acid N-carboxy anhydrides of (2S,3S)-β-substituted serines

A general access to 3-hydroxy-4-(1-hydroxyalkyl)-β-lactams with a C4-C1′ relative configuration unlike is provided. The subsequent oxidative ring expansion of the corresponding 3-hydroxy β-lactam smoothly affords an α-amino acid N-ca
