Gold(I)-Catalyzed Glycosylation with Glycosyl Ynenoates as Donors

A simple and versatile glycosylation method with both armed and disarmed glycosyl ynenoates as donors is developed. Employing a gold(I) complex as catalyst with or without the assistance of TfOH, the scope of the present glycosylation protocol is very wid

O-(p-Methoxyphenylethynyl)phenyl Glycosides: Versatile New Glycosylation Donors for the Highly Efficient Construction of Glycosidic Linkages

A novel alkyne-activation-based glycosylation protocol using o-(p-methoxyphenylethynyl)phenyl (MPEP) glycoside was established. The glycosyl MPEP donors were shelf-stable and could be prepared efficiently via Sonogashira reaction from the corresponding o-

ortho-(Methyltosylaminoethynyl)benzyl glycosides as new glycosyl donors for latent-active glycosylation

A new glycosylation protocol employing ortho-(methyltosylaminoethynyl)benzyl glycosides as glycosyl donors and TMSOTf as the catalyst is disclosed. These donors can be readily prepared from the corresponding 'latent' ortho-iodobenzyl glycosides via a Sonogashira coupling, thus providing a new approach for the 'latent-active' synthesis of glycans.

Gold-catalyzed synthesis of 2-deoxy glycosides using S-But-3-ynyl thioglycoside donors

A mild and atom-economic gold(I)-catalyzed glycosylation for stereoselective synthesis of 2-deoxy α- glycosides using bench-stable 2-deoxy S-But-3-ynyl thioglycoside donors has been described. Under optimal conditions, 2- deoxy and 2,6-dideoxy thioglycoside donors were able to react with a variety of primary, secondary, and tertiary alcohol acceptors to afford α-selective glycosides in good to excellent yields.

tHE SYNTHESIS OF 2'-DEOXY-β-DISACCHARIDES: NOVEL APPROACHES

Benzylated 1,2-orthoacetates were converted by dry acetic acid into 1,2-trans-diacetates which behaved as excellent β-glycosyl donors with various non-acylated glycosyl acceptors in the presence of trimethylsilyl triflate.Deacetylation, followed by xantha

GLYCOSYLATIONS WITH N-FORMYLAMINO SUGARS: A NEW APPROACH TO 2'-DEOXY-β-DISACCHARIDES

Various derivatives of N-formyl glucosamine (β-acetate, α-chloride, α-trichloroacetimidate) are used as glycosyl donors.The resulting disaccharides are smoothly deaminated into the corresponding 2'-deoxy-β-disaccharides through intermediate isonitriles by
