pH determines selectivity: The ligation of peptide hydrazides is a new method for proteinchemicalsynthesis that is complementary to native chemicalligation. Peptide hydrazides may be the long‐sought reagent equivalent to a “thioester synthon”, one that is stable to the conditions of native chemicalligation.

We report a simple and promising synthetic method to oxidize peptide hydrazides containing N-terminal thiazolidine as a protected cysteine. This yields the corresponding thioester via a peptide azide without decomposition of the thiazolidine ring. The newly developed protocol was validated by the synthesis of the bioactive peptide LacZα.

The NY-ESO-1 (A39-A68) peptide hydrazide was prepared through 9-fluorenyl-methoxycarbonyl solid-phase peptide synthesis (Fmoc SPPS) from a new 9-fluorenyl-methoxycarbonyl hydrazine 2-chlorotrityl chloride (Fmoc-hydrazine 2CTC) resin. The new resin was ideal for long-term storage and usage in Fmoc SPPS. Besides, the title peptide hydrazide could be transformed nearly quantitatively into the corresponding peptide thioester, which was both isolable and usable directly in native chemical ligation (NCL).
