functionalized side chains, protected for synthesis by the Fmoc strategy. Solid phase aza-peptidesynthesis is demonstrated including selective mild deprotection of Ddz with Mg(ClO4)2 and coupling of the next amino acid with triphosgene. Ddz deprotection is orthogonal with the Fmoc and Boc protecting groups, making the solid phase Ddz-aza-peptide synthesis compatible with both the Fmoc and the Boc
