Benzyl 4,6-O-Benzylidene-2,3-di-O-benzyl-β-D-galactpyranoside (CAS 57783-80-9)

Benzyl 4,6-O-Benzylidene-2,3-di-O-benzyl-β-D-galactopyranoside is a chemically engineered galactose derivative used extensively in the field of synthetic organic chemistry, particularly in the study of carbohydrate structures and glycosylation reactions. This compound is characterized by its protective benzyl and benzylidene groups, which shield specific hydroxyl groups from reacting prematurely during synthetic procedures. These protective groups are pivotal for achieving selective activation and manipulation of the sugar molecule, allowing for the formation of specific glycosidic linkages with high stereochemical control. In research, this chemical is employed to explore the mechanics of glycosidic bond formation, providing insights into the synthesis of complex oligosaccharides and glycoconjugates. By facilitating the study of the reactivities of different hydroxyl groups under various conditions, it helps explain the principles behind the regioselectivity and stereoselectivity of glycosyltransferases. This, in turn, contributes to our understanding of how carbohydrates perform biological roles through precise molecular interactions, such as cell signaling and molecular recognition. Through such synthetic studies, researchers are able to model and simulate the structures and functions of naturally occurring glycosides, advancing the broader field of glycoscience.
