pubmed-article:20478556pubmed:abstractTextConformationally constrained amino acid analogs are widely used to probe the bioactive conformation of peptides. In this paper we report on the synthesis of hexafunctional allose-templated L- and D-hydroxyornithine and L- and D-hydroxyarginine analogs in which the allose-based polyol scaffold constrains the side chain of hydroxyornithine and hydroxyarginine in an extended conformation. The partially protected building blocks were selected for future use in solid-phase peptide synthesis using the Fmoc-strategy. The synthesis starts from a previously prepared C-glucosyl glycine analog. Multiple chemical protection-deprotection steps and an oxidation are used to prepare 3-keto-C-glucosyl analogs that serve as a precursor to install an amino function via reductive amination. Guanidinylation of the amino group provides access to allose-templated hydroxyarginine analogs. Both hexafunctional building blocks are further chemically modified to provide suitable protection for solid-phase peptide synthesis using the Fmoc-strategy.lld:pubmed
