On August 27, 2020, Lafuente, Leticia; Rojas, Agustin H.; Piro, Oscar E.; Echeverria, Gustavo A.; Ponzinibbio, Agustin published an article.Reference of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate The title of the article was Synthesis, NMR and X-ray studies on novel heteroaromatic aldoxime O-ether 2- and 2,3-unsaturated glycosides. And the article contained the following:
We present the synthesis of novel hydrolytically stable heteroaromatic oxime ether glycosides in very good yields and high anomeric selectivity. The products obtained are α-glycosides and the double bond configuration is E. The aldoxime O-ether carbohydrate derivatives were analyzed by structural X-ray diffraction and NMR spectral data. A complete investigation on the glycoside structures, that includes conformation characteristics in the pyranose ring and heterocyclic alternative positions, is also described. 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).Reference of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate
