In this study, the potential of N-alkoxymethyl groups as protectants for the peptide backbone has been investigated. These groups were found to be compatible with the standard conditions of Fmoc/tBu SPPS, and can be cleaved off from the peptide backbone by acids. Thus, backbone N-alkoxymethyl groups may be useful to prevent undesired side-reactions and/or interchain aggregation during peptide elongation
在该研究中,已经研究了N-烷氧基甲基基团作为肽主链保护剂的潜力。发现这些基团与Fmoc / t Bu SPPS的标准条件相容,并且可以被酸从肽主链上裂解下来。因此,主链N-烷氧基甲基可用于防止在固相上的肽延伸过程中不期望的副反应和/或链间聚集。然而,它们作为保护基应用的主要问题是难以将它们掺入肽主链中。
