title: 2-Deoxy-2-iodo-alpha-mannopyranosyl and -talopyranosyl acetates: highly stereoselective glycosyl donors for the synthesis of 2-deoxy-alpha-glycosides.
abstract: [formula: see text] TMS-OTf- or TBS-OTf-promoted glycosidation reactions of 2-deoxy-2-iodo-alpha-mannopyranosyl acetates 8-10 and the 2-deoxy-2-iodo-alpha-talopyranosyl acetate 11 provide the corresponding 2-deoxy-2-iodo-alpha-pyranosides, precursors to 2-deoxy-alpha-glycosides, as the only observed reaction products.
