  Application of the Suzuki cross‐coupling reaction for efficient synthesis of diverse substituted biaryl‐chromen‐4‐ones using an optimized palladium(0) catalyst system is reported. The coupling of arylboronic acids with the resin‐bound bromoflavanones which were prepared by organoselenium‐induced regioselective intramolecular cyclization of bromo‐2‐hydroxylchalcones proceeded smoothly. Biaryl‐chromen‐4‐ones

  A series of C-C biflavones was designed to investigate the relationship between structural array of different flavone-flavone subunit linkage and the inhibitory activity against phospholipase A(2) (PLA(2)). Among six classes of C-C biflavones designed, four classes of C-C biflavones, which have flavone-flavone subunit linkages at A ring-A ring, A ring-B ring, B ring-B ring, and B ring-C ring, were synthesized. The synthetic biflavones exhibited somewhat different inhibitory activities against sPLA(2)-IIA. Among them, the biflavone a having a C-C 4'-4' linkage showed comparable inhibitory activity with that of the natural biflavonoid, ochnaflavone, and 7-fold stronger activity than that of amentoflavone. Further chemical modification is being carried out in order to obtain the chemically optimized biflavonoids. (C) 2006 Elsevier Ltd. All rights reserved.
