excellent purity of the final products. The described strategy allows the preparation of short peptide sequences keeping the chiral integrity of amino acid precursors. Compatibility of nosyl group with the side-chain protecting groups used in Fmoc-based strategy is demonstrated. The method here presented is an alternative strategy that could provide advantages for future peptide synthesis.
已经开发了在溶液相中高效且实用的肽合成方法。该过程是基于使用的p -nitrobenzenesulfonyl(硝基苯磺酰基)基团为α氨基酸的氨基官能团的保护。该方法的每一步,其特征在于通过收端基保护氨基功能,形成肽键并去除磺酰胺基,其特征在于高收率和最终产物的优异纯度。所描述的策略允许制备保持氨基酸前体的手性完整性的短肽序列。证明了nosyl基团与基于Fmoc的策略中使用的侧链保护基团的相容性。本文介绍的方法是一种替代策略,可为将来的肽合成提供优势。
