Stereoselective synthesis of (5R,6R)- and (5S,6S)-5-benzylamino-6-(tert-butyldimethylsilanyloxymethyl)-5,6-dihydropyran-2-ones starting from D-glucal and furanaldehyde, respectively, is described. The synthesis relies on a Sharpless asymmetric dihydroxylation, an Achmatowicz reaction, and a stereoselective Pd-catalyzed allylic amination as the key steps. (C) 2010 Elsevier Ltd.
