Submonomer synthesis of aza-peptides featuring regioselective alkylation of peptide-bound aza-Gly residues provided ten aza-analogues of the Growth Hormone Releasing Peptide-6 (GHRP-6) in 15−42% yield and purity generally ≥90%. Circular dichroism demonstrated that azaPhe-peptide 7a induced a β-turn conformation which may be responsible for its 1000-fold improvement in GHRP-6 selectivity for the CD36
