CAS 20881-04-3: 1,2:3,5-Di-O-isopropylidene-alpha-D-xylofuranose

Description: 1,2:3,5-Di-O-isopropylidene-alpha-D-xylofuranose is a carbohydrate derivative, specifically a protected form of the sugar xylose. This compound features two isopropylidene protective groups, which are used to shield the hydroxyl groups on the sugar molecule, enhancing its stability and reactivity in synthetic applications. The presence of these protective groups allows for selective reactions at specific sites on the sugar, making it valuable in organic synthesis, particularly in the preparation of glycosides and other carbohydrate-based compounds. The compound exists in a furanose form, indicating a five-membered ring structure, which is typical for many sugars in their cyclic forms. Its alpha configuration refers to the orientation of the hydroxyl group at the anomeric carbon, which plays a crucial role in determining the reactivity and properties of the sugar. As a chemical substance, it is typically a white to off-white solid and is soluble in organic solvents. Its applications extend to the fields of medicinal chemistry and carbohydrate chemistry, where it serves as an intermediate in the synthesis of more complex molecules.
