first total synthesis of YM-280193, a cyclic depsipeptide that inhibits the ADP-induced aggregation of human platelets, is described. The monomer and dipeptide fragments were prepared using conventional chemistry and subsequently assembled by Fmoc-solid-phase peptide synthesis (Fmoc-SPPS). A late-stage novel bis-alkylation–elimination of cysteine on-resin was employed to introduce the unnatural N-methyldehydroalanine

their numerous applications, fluorinated amino acids have recently attracted significant attention. The preparation of fluorine-containing phenylalanines, heteroaryl alanines and aliphatic fluorinated amino acids using Mitsunobu–Tsunoda alkylation of a chiral nucleophilic glycine equivalent with readily available alcohol substrates is described. The reaction proceeds in high yields and with excellent

α-Disubstituted alkenyl aminoacidderivatives (e.g. Fmoc-S5-OH) are valuable monomers in the construction of stapled peptide derivatives. Synthetic access to these is possible using the Ni-[(Benzylprolyl)amino]benzophenone (BPB) complex as a chiral auxiliary. We discuss a reappraisal of the use of this, and demonstrate that epimerisation of the proline α-centre occurs during formation of the complex, leading to
