Double glycosylation of cysteine-containing peptides has been carried out by a one-pot two-step sequence comprising selective S-propargylation followed by photoinduced (λ max 365 nm) free-radical hydrothiolation with glycosyl thiols. Conditions were established for the sequential introduction of two different thiol residues such as a glycosyl and a biotinyl derivative.

Abstract
Double glycosylation of cysteine-containing peptides has been carried out by a one-pot two-step sequence comprising selective S-propargylation followed by photoinduced (λ max 365 nm) free-radical hydrothiolation with glycosyl thiols. Conditions were established for the sequential introduction of two different thiol residues such as a glycosyl and a biotinyl derivative.File in questo prodotto:
