On November 30, 2019, Singh, Adesh Kumar; Venkatesh, Rapelly; Kandasamy, Jeyakumar published an article.Application In Synthesis of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate The title of the article was Palladium-Catalyzed One-Pot Stereospecific Synthesis of 2-Deoxy Aryl C-Glycosides from Glycals and Anilines in the Presence of tert -Butyl Nitrite. And the article contained the following:
The palladium-catalyzed one-pot synthesis of 2,3-deoxy-3-keto aryl C-glycosides is achieved from glycals and anilines in the presence of tert-Bu nitrite and aqueous HBF4 under mild conditions. This one-pot method stereospecifically provides α- and β-aryl glycosides (â?9:1 by NMR) in good yields at room temperature The configuration at the C-3 position in the glycal determines the anomeric selectivity (i.e., α or β) of the desired products. 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).Application In Synthesis of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate
