The [Tyr40] preprorenin (40-50) peptide methyl ester, an undecapeptide related to the human renin prosegment, has been synthesized using a stepwise strategy with hydrogenolisable protections on the side chains. The final deprotection was very difficult as observed by 1H NMR and reversed phase HPLC. 2D 1H NMR spectroscopy of the purified peptide allowed the assignment of all protons.
