Unprecedented magnesium dihalide-catalysed Claisen rearrangement of 2-alkoxycarbonyl allyl vinyl ethers derived from α-chloroglycidic esters is reported in the glucidic series. A first application of this reaction concerns the stereoselectiveconstruction of a disaccharide analogue including a galactosyl and an ulosonic isopropyl ester moieties.
