Abstract
A highly efficient protocol for Arndt-Eistert chain elongation of the base-labile fluorenylmethoxycarbonyl (Fmoc) protected alpha-amino acid s by Ag+-catalyzed, ultrasound-promoted Wolff rearrangement of the cor responding alpha-diazo ketones at room temperature is described. The e nantiomeric purity of the products was examined by capillary zone elec trophoresis with chiral buffer systems.
