  A practical access to glucose- and allose-based (5+5) 3-spiropseudonucleosides from a common intermediate

  摘要：

  A practical access to glucose-based and allose-based spirooxazolidinones is reported. The synthetic sequence consisting of TEMPO-catalyzed oxidation of 1,2: 5,6-di-O-isopropylidene-alpha-D-glucofuranose, Henry reaction, and reduction provides amino alcohol with allo-configuration on a multigram scale. Alternatively, water elimination from Henry products followed by a rehydration gives an access to diastereomerically pure glucose-based nitro alcohol which upon reduction provides complementary amino alcohol with gluco-configuration. The latter amino alcohols are transformed into spirooxazolidinones (3-spiropseudonucleosides) via their N-Cbz or N-phenylcarbamate derivatives. The title compounds easily undergo N-derivatization and give highly crystalline materials. Two of the newly obtained (5+5) 3-spiropseudonucleosides are characterized by X-ray crystallography.
