Abstract
The chemoselective transformation of Trp9 and Trp11, located at the hydrophobic core of the antiparallel, double helical pore of O-acetyl gramicidin A(HCO-ValGlyAlaLeuoAlaValoValValo TrpLeuo TrpLeuoTrpLeuoTrpNHCH2CH2OAc; o = D isomer) to Asp9 gramicidin and Asp9 Asp11 gramicidin has been demonstrated by oxidation with 0.25 eq. of in situ generated Ru(VIII), HPLC isolation, amino acid analysis and peptide sequencing.
