2,3-Dideoxy-hex-2-enopyranosides, also described as 2,3-unsaturated glycosides, constitute an important class of carbohydrate derivatives because their double bond and anomeric substituent enable diverse synthetic transformations. This review summarises recent developments in the...

The anomeric effect in carbohydrate chemistry is known as the interaction between the OHd substituent at the anomeric position to favor an axial orientation rather than an equatorial one, despite the increased 1,3-diaxial interactions. In the anomeric effect, a sugar ring is stab...

Determination of the stereochemistry of the stereocenter from the aglyconic part of carbohydrates is always one of the most important tasks for chemistry carbohydrates researchers. The absolute configuration (AC), a challenge for synthetic chemists, has attracted much attention....
