In this work the synthesis of a linear hexapeptide with a hydroxylamine functionality at the N‐terminus and a ketone instead of the carboxylic acid at the C‐terminus is described. Cyclization by ketoxime formation yields the 19‐membered ring‐expanded cyclic hexapeptide cyclo[Goly‐Val‐Ala‐Pro‐Leu‐Kly] which adopts a main conformer with two intramolecular hydrogen bonds. The hydrolytic stability of a
