Synthesis of β-amino acids: 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyl-uronium tetrafluoroborate (TBTU) for activation of Fmoc-/Boc-/Z-α-amino acids

, p. 3089 - 3096 (2007/10/03)
A new and efficient method for the homologation of urethane protected α-amino acids to its β-homomers by the Arndt-Eistert method using TBTU as a coupling agent is described. Several Fmoc-/Boc-/Z-protected α-amino diazoketone derivatives have been obtaine
Synthesis of Fmoc-β-homoamino acids by ultrasound-promoted wolff rearrangement
Müller, Annett,Vogt, Carla,Sewald, Norbert
, p. 837 - 841 (2007/10/03)
A highly efficient protocol for Amdt-Eistert chain elongation of the base-labile fluorenylmethoxycarbonyl (Fmoc) protected α-amino acids by Ag+- catalyzed, ultrasound-promoted Wolff rearrangement of the corresponding α- diazo ketones at room temperature is described. The enantiomeric purity of the products was examined by capillary zone electrophoresis with chiral buffer systems.
