Synthesis of new UV-B light absorbents: (Acetylphenyl)glycosides with antioxidant activities.
m-Acetylphenyl-beta-d-glucopyranosides and m-acetylphenyl-alpha/beta-d-mannopyranosides were synthesized by the Koenigs-Knorr, Mitsunobu, and Helferich reactions as key glycosylation reactions, respectively. Their spectroscopic properties and antioxidative activities were characterized as potential ultraviolet B-ray absorbents.
