“…Since the reaction proceeds via an oxycarbonium intermediate, thiols, halides and other nucleophiles can be employed besides alcohols to produce corresponding glycosides (see López et al, 1995;Yadav et al, 2001). The pseudoglycal products from the Ferrier rearrangement reaction have been used as chiral building blocks in the synthesis of antibiotics (see Domon et al, 2005), oligosaccharides (see Danishefsky & Bilodeau, 1996;Griffith & Danishefsky, 1991;Halcomb et al, 1995), nucleosides (see Bracherro et al, 1998), glycopeptides (see Dorgan & Jackson, 1996;Chambers et al, 2005) and also as chiral ligands in asymmetric synthesis (see Minuth & Boysen, 2009).…”
