We herein reported a new type of S-o-(p-methoxyphenylethynyl)benzyl donor for highly efficient glycosylation method. The was activated by 10% Tf2O and underwent with various acceptors to provide the corresponding glycosides in excellent yield. Furthermore, two repetitive fragments Polyporus umbellatus polysaccharides (PUPs), isolated from traditional Chinese medicine "Polyporus umbellatus", were prepared combining "single-catalyst one-pot" "latent-active" strategies first time future clear studies on structure-activity relationship PUPs.
