An enantioselective synthesis of a 5-LO inhibiting chiral hydroxyurea is described based on the nucleophilic addition of dimethylsulfoxonium ylide to a nitrone bearing a mannose-derived chiral auxiliary. The dihydrobenzofuran skeleton is then constructed by a spontaneous cyclization of the initial adduct, thus completing a tandem nucleophilic addition-cyclization protocol.
