Thioester and selenoester generators, precursors thereof, thioester and selenoester compounds produced therefrom, and related methods for their production are provided. The subject thioester and selenoester generators include an amino acid synthon having an N-terminal group joined to a C-terminal group through an organic backbone comprising one or more carbons. The organic backbone contains a backbone nitrogen, anchored to a support through a nucleophile-stable linker that lacks reactive functional groups. The organic backbone may include a target molecule of interest, such as an amino acid, peptide, polypeptide or other organic compound of interest, and/or the N- and/or C-termini can be elaborated using a variety of synthesis approaches to provide a target molecule of interest. The compounds and methods find a wide variety of uses, including use in thioester- or selenoester-based chemical ligation techniques.
本发明提供了硫酯和硒酯生成物、其前体、由此生成的硫酯和硒酯化合物以及相关的生产方法。所述硫酯和硒酯生成物包括一种氨基酸合体,其 N 端基团通过包含一个或多个碳原子的有机骨架与 C 端基团相连。有机骨架包含一个骨架氮,通过缺乏活性官能团的亲核稳定连接体锚定到支持物上。有机骨架可包括感兴趣的目标分子,如氨基酸、肽、多肽或其他感兴趣的有机化合物,和/或可使用各种合成方法精心制作 N 端和/或 C 端,以提供感兴趣的目标分子。这些化合物和方法用途广泛,包括用于基于硫酯或硒酯的化学连接技术。
