The preparation of bicyclic carbohydrate mimics related to (+)-castanospermine incorporating a thiohydantoin moiety is reported. The syntheticapproach is compatible with molecular diversity-oriented strategies and involves α-azidoesters, built at the C-5/C-6 segment in gluco- or galactofuranose scaffolds, as the key precursors. Reduction to the corresponding α-amino ester and in situ coupling with
