A new strategy for the synthesis of biflavonoids via arylboronic acids
Muller, Dominique,Fleury, Jean-Pierre
, p. 2229 - 2232 (2007/10/02)
Amentoflavone derivatives were prepared by catalytic coupling of 8-flavone-boronic acids with iodoflavones. 3-Arylflavones, as biflavonoid synthon, are accessible by the method.
