Enantiospecific synthesis of heterocyclic compounds: An approach to functionalised tetrahydrofurans from intramolecular dipolar cycloadditions

Intramolecular cycloaddition of the nitrone 8, derived from the glucal 1, produces stereospecifically the isoxazolidins 9, which may be reductively cleaved to afford functionalised aminotetrahydrofuran polyols such as 20 and 23.

Allylic Nucleophilic Substitution Reactions in Sugars. III. Uncatalysed Displacements in Hexamethylphosphoramide

The uncatalysed displacement of allylic benzoyloxy groups with azide in unsaturated sugars has been studied by using hexamethylphosphoramide as solvent.Tri-O-benzoylglycals and 4,6-O-benzylidene-3-O-benzoylglycals were investigated.The former gave rise to

ALLYLIC SUBSTITUTIONS IN TRI-O-BENZYL-GLYCALS, 4,6-OBENZYLIDENE-GLYCALS AND RELATED COMPOUNDS

3,4,6-Tri-O-benzyl-D-glucal and the benzyl 4,6-di-O-benzyl-2,3-dideoxy-hex-2-enopyranosides react with sodium azide in acetonitrile under boron trifluoride catalysis to yield mixtures of 3-azido-glycals and 2,3-unsaturated glycosyl azides.Similar reaction
