    摘要: The invention is directed to nucleophile-stable thioester generating compounds comprising a carboxyester thiol. The compounds have wide applicability in organic synthesis, including the generation of peptide-, polypeptide- and other polymer-thioesters. The invention is particularly useful for generating activated-thioesters from precursors that are made under conditions in which strong nucleophiles are employed, such as peptides or polypeptides made using Fmoc SPPS, as well as multi-step ligation or conjugation schemes that require (or benefit from the use of) compatible selective approaches for directing a specific ligation or conjugation reaction of interest.
