Synthesis of Thiohydantoin-Castanospermine Glycomimetics as Glycosidase Inhibitors
The Journal of Organic Chemistry, 2009 The preparation of bicyclic carbohydrate mimics related to (+)-castanospermine incorporating a thiohydantoin moiety is reported. The synthetic approach is compatible with molecular diversity-oriented strategies and involves alpha-azidoesters, built at the C-5/C-6 segment in gluco- or galactofuranose scaffolds, as the key precursors.
