The Fmoc (9-fluorenylmethyloxycarbonyl) strategy is a widely adopted method within Fmoc solid-phase peptide synthesis. It involves protecting the alpha-amino group of incoming amino acids with the Fmoc group, which can be selectively removed under mild basic conditions. This allows for the sequential addition of amino acids to the growing peptide chain, which is attached to a solid support. This iterative process, involving deprotection and coupling steps, is fundamental to building the target peptide sequence.作者：R Dickman·2019·被引用次数：50—28 We have developed a powerfulsolid-phase peptide synthesis(SPPS) strategy for thesynthesisof lanthionine- containingpeptides.29 This is ...
