2,3,4-Tri-O-acetyl-ù-D-xylopyranosyl bromide

Description:

2,3,4-Tri-O-acetyl-β-D-xylopyranosyl bromide is a chemical compound that belongs to the class of glycosides, specifically a halogenated sugar derivative. It is characterized by the presence of a β-D-xylopyranosyl moiety, which is a six-membered cyclic form of the sugar xylose, acetylated at the hydroxyl groups on the 2, 3, and 4 positions. The bromide substituent indicates that it is a brominated derivative, which can enhance its reactivity in various chemical reactions, particularly in glycosylation processes. This compound is typically used in organic synthesis and carbohydrate chemistry, serving as a glycosyl donor in the formation of glycosidic bonds. Its acetyl groups provide protection for the hydroxyl groups, making it a useful intermediate in the synthesis of more complex carbohydrates or glycosides. The compound is generally stable under standard laboratory conditions but should be handled with care due to the presence of the bromide, which can be hazardous.
