Abstract
Introducing glycans represents an efficient chemical approach to improve the pharmacological properties of therapeutic biomolecules. Herein, we report an efficient synthesis of glycoconjugates through chlorooxime-thiol conjugation. The reactive glycosyl chlorooximes, derived from pyranoses or furanoses, readily couple to a wide range of thiol-containing substrates, including peptides, sugars, and thiophenols. This method features mild reaction conditions and fast kinetics. Capability for aqueous media and gram-scale synthesis demonstrates the potential of this method in the bioconjugation of saccharides with biologically active molecules.
