TL;DR: Fe2(SO4)3···xH2O catalyzes the Ferrier reaction of per−O−acetylated/benzylated glycals with alcohols to give 2,3−unsaturated α−glycosides in a few minutes under microwave irradiation as mentioned in this paper.

TL;DR: In this paper, the Ferrier reaction of O -1,3-dienyl acetals with n-butyllithium was shown to yield α-quaternary-β,γ-unsaturated aldehydes with high α-regioselectivities.

TL;DR: Amberlyst 15 serves as an inexpensive, effective, and environmentally friendly catalyst in converting 3,4,6,tri-O-acetyl-D-glucal into 2,3,unsaturated O and S-glycosides via Ferrier rearrangement in moderate to excellent yields with high α selectivity as discussed by the authors.

TL;DR: Amino acid 2,3-unsaturated glycopyranosyls have been prepared by the Ferrier rearrangement of acetyl protected glucals and PEG-bound amino acids in the presence of a catalytic quantity of BF3·Et2O in CH2Cl2 at ambient temperature.
