Ethyl 2,3,4-Tri-O-benzyl-1-thio-α,β-L-fucopyranoside (CAS 169532-17-6)

Ethyl 2,3,4-Tri-O-benzyl-1-thio-α,β-L-fucopyranoside is a synthetic sugar derivative extensively utilized in carbohydrate chemistry for the study of glycosylation processes and the synthesis of thio-linked glycoconjugates. This compound is characterized by its ethyl thio-glycoside moiety, which provides a sulfur atom at the anomeric position, replacing the more common oxygen atom found in natural glycosides. This sulfur substitution introduces unique chemical reactivity that is exploited in various synthetic pathways, particularly in forming glycosidic bonds that are resistant to enzymatic degradation. The benzyl groups at the 2, 3, and 4 positions serve as protective groups, stabilizing the sugar molecule during chemical reactions and allowing for selective deprotection and further modification. This selective protection is crucial for the stepwise construction of complex carbohydrate structures. In research, this compound has been used to explore new methodologies for glycoside synthesis, offering insights into alternative bonding strategies that expand the utility of carbohydrates in materials science and synthetic biology. Specifically, Ethyl 2,3,4-Tri-O-benzyl-1-thio-α,β-L-fucopyranoside has facilitated the development of new glycomaterials and biosensors by providing a stable scaffold that can interact with biological systems without natural decomposition pathways. This has significantly advanced the field of glycoengineering, where precise sugar modifications are necessary to study and manipulate cellular interactions and signaling pathways.
