  Isothiocyanato derivatives of sugars in the stereoselective synthesis of spironucleosides and spiro-C-glycosides

  摘要：

  A stereocontrolled synthesis of pyranoid and furanoid spironucleosides and spiro-C-glycosides (D-ribo and D-arabino configurations) of oxazolidines, oxazolines and perhydrooxazines via isothiocyanato sugar derivatives is reported. The intermediate isothiocyanates are prepared from sugar spiroketals by stereoselective opening of the acetal ring with trimethylsilyl N- and C-nucleophiles, and later formation of the isothiocyanato group.

• Stereocontrolled synthesis of thiohydantoin spironucleosides from sugar spiroacetals

  5-Epithiohydantocidin, N-alkyl and N-glycosylthiohydantoin spironucleosides are prepared from glycosylaminoesters and from furanoid and pyranoid methyl isothiocyanatoulosonates. The aminoesters; and the isothiocyanates are obtained, in a stereocontrolled manner, from sugar spiroacetals through a high-yielding sequence involving ring opening with trimethyl azide, formation of an ester group, reduction of the azide, and, in the case of isothiocyanates, reaction with thiophosgene.
