Stereoselective glycosylation is challenging in carbohydrate chem. Herein, stereoselective thioglycosylation of glycals via palladium-catalyzed allylic rearrangement yields various substituents on α-isomer thioglycosides. Two comprehensive series of aryl and benzyl thioglycosides were obtained via a combination of thiosulfates with glycals derived from glucose, arabinose, galactose, and rhamnose. Furthermore, diosgenyl α-L-rhamnoside and isoquercitrin achieved selectivity via stereospecific [2,3]-sigma rearrangements of α-sulfoxide-rhamnoside and α-sulfoxide-glucoside, resp. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Electric Literature of 2873-29-2

And the article contained the following:

An efficient three component coupling of aromatic aldehyde, deoxy sugar based alkyne (α-2-deoxy propargyl glycoside) and heterocyclic amine have been refluxed to synthesize stereoselective chiral propargylamine with good to excellent yield using only CuI catalyst along with bifunctional ligand L-proline. This method has proved to be applicable in wide range of substrates and found highly enantioselective with respect to earlier reported methods. In addition, L-proline was found as a chiral source which demonstrated that it could be developed as a highly enantioselective method for the construction of deoxy sugar based chiral propargylamine. The ligand L-proline was used for the first time in enantioselective A3-coupling reaction of α-2-deoxy propargyl glycosides involving substituted aromatic aldehyde and heterocyclic amines. Herein, we have synthesized 15 novel compounds based on A3-coupling reaction and structures of all the enantioselective compounds were characterized by TLC and NMR spectroscopy. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Quality Control of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate
