A highly efficient protocol for Arndt-Eistert chain elongation of the base-labile fluorenylmethoxycarbonyl (Fmoc) protected alpha-amino acids by Ag+-catalyzed, ultrasound-promoted Wolff rearrangement of the corresponding alpha-diazo ketones at room temperature is described. The enantiomeric purity of the products was examined by capillary zone electrophoresis with chiral buffer systems.
