Expedient synthesis of threo-β-hydroxy-α-amino acid derivatives: Phenylalanine, tyrosine, histidine, and tryptophan

An expedient synthesis of enantiomerically pure threo-β-hydroxy- α-amino acid derivatives of phenylalanine, tyrosine, histidine, and tryptophan is described. The NBS-mediated radical bromination of the N,N-di-tert-butoxycarbonyl protected α-amino acids an
