Syringin (1), a natural bioactive glucoside isolated from the root of Acanthopanax senticosus (Rupr. Maxim.) Harms, possesses significant anti-inflammatory activity. In this study, we have accomplished the total syntheses of syringin (1), along with its natural analogues 2-12, from a common starting material, syringaldehyde (13), in 4-8 steps with an overall yields of 11.8-61.3%. The anti-inflammatory activities of these compounds were determined against NO production in the LPS-stimulated RAW264.7 cells. Among them, compounds 1-5, 7, and 9 exhibited different levels of anti-inflammatory activity.

4-Allyl-2,6-dimethoxyphenol and related compounds have been subjected to anodic oxidation to afford a number of oxidation products including asatone-type neolignans, heterotropanone-type compounds and arylpropanoids.Furthermore, the formation processes of these oxidation products are shown to involve both radical and cationic reactions which are dependent upon the applied potentials, solvent media and substituents on the aromatic ring.Keywords - allylphenol; neolignan; electrochemical oxidation; Diels-Alder reaction; biomimetic synthesis
