On May 21, 2021, Perali, Ramu Sridhar; Boddu, Umamaheswara Rao; Sankar, Drisya Chittadi published an article.COA of Formula: C12H16O7 The title of the article was [1,2]- vs [2,3]-Wittig Rearrangement in Carbohydrate Derived Alkenyl Systems. And the article contained the following:
A simple and efficient strategy for the regio- and stereoselective synthesis of carbon-branched sugar derivatives is described. The successful implementation of Wittig rearrangement on substrates derived by Ferrier rearrangement of various glycals and 3-O-alkenyl glycals is studied extensively. A highly selective [1,2]- or [2,3]-Wittig rearrangement is revealed that provides a novel class of stereo-defined 3-C-branched glycals and C-glycosides, which are otherwise difficult to obtain. 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).COA of Formula: C12H16O7
The Article related to crystal structure glycoside preparation, wittig alkenyl stereoselective ferrier rearrangement glycal glycoside preparation, Carbohydrates: Glycosides and other aspects.COA of Formula: C12H16O7
