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.
