The invention relates to novel branched amino acids and novel methods for their production. The amino acids are useful in the preparation of non-natural peptides and peptidomimetics, by efficient synthesis methodology allowing good enantiomeric specificity at the alpha carbon. Typically the stereochemistry at the alpha carbon is at least 85%, preferably at least 95%, such as in excess of 99% enantiomerically pure. L-stereochemistry at this location is convenient as most biological interactions will favour this configuration, but the invention also extends to enantiomerically enriched and preferably at least 85%, preferably at least 95% such as at least 99% enantiomerically pure D stereoconfiguration. Compounds of the invention will find utility in the preparation of non-natural peptides and peptidomimetics, such as those used in the exploration of receptor specificity and activity or in peptidomimetic inhibitors of enzyme function. The compounds of the invention are built into such peptides/peptidomimetics using standard peptide chemistry.
该发明涉及新型分支型氨基酸及其制备的新方法。这些氨基酸在非天然肽和肽类似物的制备中非常有用,通过高效的合成方法,在α碳处具有良好的对映体特异性。通常,α碳的立体化学至少为85%,最好至少为95%,例如超过99%的对映纯。在这个位置的L-立体化学很方便,因为大多数生物相互作用都会偏向于这种配置,但该发明也扩展到对映富集的、优选至少为85%、最好至少为95%,例如至少为99%的对映纯D立体构型。该发明的化合物将在标准肽化学中被构建成这样的肽/肽类似物。该发明的化合物将在非天然肽和肽类似物的制备中发挥作用,例如在探索受体特异性和活性或肽类似物酶功能抑制剂中使用。
