Glycosyl phenylthiosulfonates (Glyco-PTS): novel reagents for glycoprotein synthesisThis is one of a number of contributions from the current members of the Dyson Perrins Laboratory to mark the end of almost 90 years of organic chemistry research in that building, as all its current academic staff move across South Parks Road to a new purpose-built laboratory.Electronic supplementary information (ESI) available: experimental procedures, characterization, protein ESI-MS spectra and crystal data.

Abstract

Controlled site-selective glycosylation can be achieved by combining site-directed cysteine mutagenesis with chemical modification of the introduced thiol; a new class of more efficient chemoselective reagents, glycosyl phenylthiosulfonates, allow rapid glycosylations of representative simple thiols, peptides and proteins.
