Reversible attachment of solubilizing tags to hydrophobic peptides to facilitate their purification and ligation is an essential yet challenging task in chemical protein synthesis. The efficient palladium-assisted removal of the solubilizing tag linked to the Cys side chain is reported. The strategy was applied for the efficient preparation of histone protein H4 from two fragments via one-pot operation of ligation, removal of the solubilizing tag, and desulfurization.
