On January 25, 2021, Bhuma, Naresh; Lebedel, Ludivine; Yamashita, Hiroki; Shimizu, Yutaka; Abada, Zahra; Arda, Ana; Desire, Jerome; Michelet, Bastien; Martin-Mingot, Agnes; Abou-Hassan, Ali; Takumi, Masahiro; Marrot, Jerome; Jimenez-Barbero, Jesus; Nagaki, Aiichiro; Bleriot, Yves; Thibaudeau, Sebastien published an article.SDS of cas: 2873-29-2 The title of the article was Insight into the Ferrier Rearrangement by Combining Flash Chemistry and Superacids. And the article contained the following:
The transformation of glycals into 2,3-unsaturated glycosyl derivatives, reported by Ferrier in 1962, is supposed to involve an α,β unsaturated glycosyl cation, an elusive ionic species that has still to be observed exptl. Herein, while combination of TfOH and flow conditions failed to observe this ionic species, its extended lifetime in superacid solutions allowed its characterization by NMR-based structural anal. supported by DFT calculations This allyloxycarbenium ion was further exploited in the Ferrier rearrangement to afford unsaturated nitrogen-containing C-aryl glycosides and C-alkyl glycosides under superacid and flow conditions, 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).SDS of cas: 2873-29-2
