Synthesis of some new biflavonoids. IV. Synthesis of 3,3"-biflavone

Biflavones I (R = Ph, 4-MeOC6H4) were prepd. from diketone II (R1 = Me, R2 = H) via rearrangement of II (R1 = Bz, 4-MeOC6H4CO, R2 = H) to II (R1 = H, R2 = Bz, 4-MeOC6H4CO). [on SciFinder (R)]

    Keywords: Flavonoids Role: SPN (Synthetic preparation) ; PREP (Preparation) (bi- ; chamaejasmine analogs ; prepn. of) ; chamaejasmine analog biflavone
