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。

An efficient, general, and racemization free method of covalently attaching N α -Fmoc protected amino acids to solid supports for peptidesynthesis is described. The process involves the preparation of 2,4-dichlorophenyl-N α -Fmoc-aminoacyl-4-oxymethyl-phenoxy acetates which can be used to directly and efficiently acylate amine functionalized polymers.
