Synthesis of lipopeptides using hydrazone chemical ligation.
In this paper we report that a hydrazinopeptide synthesized using solid-phase N-electrophilic amination with N-Boc-3-(4-cyanophenyl)oxaziridine reacted with a lipophilic peptide aldehyde to give the corresponding hydrazone plus an unexpected 1,3,4-oxadiazolidinopeptide containing two peptide aldehyde units. This methodology allows the synthesis of large lipopeptides.
