group, this protection is stable in acid but it is cleaved readily by zinc–aceticacid, by mercury(II) acetate, by iodine, and by electrolytic reduction. N(lm)-Diphenyl-4-pyridylmethyl-L-histidine derivatives (9)–(13) are also reported; the protecting group is again stable to acid but cleaved by hydrogenolysis, by zinc–aceticacid, and by electrolytic reduction, and it has been used in the synthesis
