Two synthetic strategies employing organometallic addition to hemiacetalic sugars followed by selective nucleophilic displacement or conjugate addition of ammonia to conjugate aldonic esters as key steps, are used. The new compounds were assayed for their inhibitory activity towards 13 commercially available glycosidases. Compounds that share the absolute configuration at C(2,3,4,5) of L-fucopyranosides and incorporate aromatic moieties are potent and selective inhibitors of alpha-L-fucosidases in the nM range.Aza-C-DisaccharidesGlycosidase InhibitorsStereoselective-SynthesisBiological EvaluationL-FucoseEnantioselective SynthesisColorectal-CancerCystic-FibrosisDiscoveryPotentSynthesis of novel pyrrolidine 3,4-diol derivatives as inhibitors of alpha-L-fucosidasestext::journal::journal article::research article
