4,6-O-Ethylidene-alpha-D-glucopyranose

It often serves as an intermediate in carbohydrate chemistry to achieve regioselective reactions on the remaining hydroxyl groups. The compound plays an important role in the synthesis of glycosides and other complex sugar-based molecules. 4,6-O-Ethylidene-α-D-glucopyranose is a protected glucose derivative in which the 4- and 6-hydroxyl groups are linked by an ethylidene acetal.
