Abstract A new anti-inflammatory active phenylpropenoid, (R,E)-1-[4-(3-hydroxyprop-1-enyl) phenoxyl]-3-methylbutane-2,3-diol (1), isolated from the stem wood of Zanthoxylum integrifoliolum, has been synthesized for the first time using commercially available 4-hydroxy benzaldehyde (2). The key step involves the Sharpless asymmetric dihydroxylation of olefin (3).
