O,O-dimethylthiophosphonosulfenyl bromide-silver triflate: a new powerful promoter system for the preactivation of thioglycosides.
نویسندگان
چکیده
O,O-Dimethylthiophosphonosulfenyl bromide (DMTPSB) in combination with silver triflate provides a powerful thiophilic promoter system. Both "armed" and "disarmed" thioglycoside glycosyl donors can be activated to form glycosidic linkages efficiently by the pre-activation protocol. The usefulness of this new promoter is illustrated by a successful iterative one-pot oligosaccharide assembly.

Synthesis of Disaccharide Nucleosides Utilizing the Temporary Protection of the 2',3'-cis-Diol of Ribonucleosides by a Boronic Ester.
Disaccharide nucleosides are an important class of natural compounds that have a variety of biological activities. In this study, we report on the synthesis of disaccharide nucleosides utilizing the temporary protection of the 2',3'-cis-diol of ribonucleosides, such as adenosine, guanosine, uridine, 5-metyluridine, 5-fluorouridine and cytidine, by a boronic ester. The temporary protection of th...
متن کاملSynthesis of L-daunosamine and L-ristosamine glycosides via photoinduced aziridination. Conversion to thioglycosides for use in glycosylation reactions.
Application of photoinduced acylnitrene aziridination to the syntheses of L-daunosamine and L-ristosamine glycosides is reported. Photoreaction of methyl 4-O-azidocarbonyl-2,3,6-trideoxy-L-hex-2-enopyranosides, followed by aziridine opening, leads to 3-amino-3-N-,4-O-carbonyl-2,3,6-trideoxy precursors to the aminosugar methyl glycosides. Conversion of these precursors to their thioglycoside ana...

Multiple Sclerosis (MS) is an autoimmune disease, which is characterized by demyelination and neuroinflammation. Extracellular Matrix (ECM) have important role in the central nervous system (CNS). Alterations are happening to the ECM after the CNS disorder like MS, Alzheimer and other neural injury. Tenasin-C (TnC) is a glycoprotein that is highly expressed in inflammatory conditions of the CNS...
