Substitution-with-Allylic-Rearrangement Reactions of Glycal Derivatives
TL;DR: Glycals (or usually their O-substituted derivatives) are readily converted into 2,3-unsaturated glycosyl compounds with O-, C-, N-, S- or otherwise linked substituents at the anomeric position as discussed by the authors.

Microwave-induced, Montmorillonite K10-catalyzed Ferrier rearrangement of tri-O-acetyl-d-galactal: mild, eco-friendly, rapid glycosidation with allylic rearrangement
TL;DR: Montmorillonite K10 was found to catalyze, under microwave irradiation, rapid O-glycosidation of 3,4,6-tri-O-acetyl-d-galactal to afford exclusively the alkyl and aryl 2,3-dideoxy-dthreo-hex-2-enopyranosides with very high α-selectivity as mentioned in this paper.

New approach to C-aryl glycosides starting from phenol and glycosyl fluoride. Lewis acid-catalyzed rearrangement of O-glycoside to C-glycoside
TL;DR: In this paper, Cp 2 HfCl 2 -AgClO 4 is particularly effective for this conversion, which leads to initial O-glycoside formation followed by rearrangement to C-congener.
