The one-pot conversion of readily available α-aminoacid into β-amino acid derivatives was carried out in good yields. The method is a sequential process initiated by a tandem radical decarboxylation−oxidation reaction; the resulting acyliminium ion was trapped by silyl ketenes. Stoichiometric and catalytic versions of this reaction were developed and then applied to prepare modified di- and tripeptides
