Huazhongilexone is not 3′,5,5′,7-tetrahydroxyflavanone. Preparation of 3′,5′-dimethoxy-5,7-dihydroxyflavanone

Huazhongilexone, isolated from Ilex centrochinensis, was originally assigned the structure 3′,5,5′,7-tetrahydroxyflavanone. The racemic flavanone has been synthezised. Huazhongilexone is different from the synthetic compound and thus must have a different structure. In addition the new (±)-3′,5′-dimethoxy-5,7- dihydroxyflavanone has been prepared and characterized.
