A new series of thio-substituted sugars were synthesised relying on the totally regio- and stereoselective cycloaddition of 4-deoxyhex-4-enopyranose derivatives to ‘in situ’ generated oxothiones. Conformational studies of the above unsaturated sugars showed a marked prevalence of the all-axial conformer.

Abstract
A new series of thio-substituted sugars were synthesised relying on the totally regio- and stereoselective cycloaddition of 4-deoxyhex-4-enopyranose derivatives to ‘in situ’ generated oxothiones. Conformational studies of the above unsaturated sugars showed a marked prevalence of the all-axial conformer.File in questo prodotto:
