A multicomponent Knoevenagel–aza-Michael cyclocondensation (KaMC) reaction starting from Meldrum's acid has been developed with base-sensitive N-Fmoc-hydroxylamine. The reaction takes place under very mild basic conditions, providing a straightforward synthetic route to various unprecedented N-Fmoc-isoxazolidin-5-ones. Subsequent chemoselective reductive cleavage of the N–O bond in the presence of Zn/AcOH allowed a short synthesis of the corresponding N-Fmoc-β-amino acids.

The most commonly recognized motifs in protein-protein interactions are γ and β turns, which are defined by three to four contiguous amino acids in a peptide sequence. Cyclic tetrapeptides thus represent minimalist turn mimetics, but their usefulness is c
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

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
