Chemical ligation is an important bottleneck reaction in peptide chemistry. The ­authors have developed a synthesis of O-acyl hydroxamic acids, which can be converted into the corresponding N-hydroxy peptides.



O-Acyl hydroxamic acids were prepared from amino acids and N-(tert-butyl)hydroxylamine. Furthermore, deprotection of an Fmoc group from the O-acyl hydroxamic acids with subsequent formation of a new peptide bond proceeds smoothly.
