Synthesis of some new biflavonoids. I. Synthesis of the aromatic 1,4-diketones

Five arom. 1,4-diketones I [R = 2,4,6-(MeO)3, H, 4-Me, 4-MeO, 2,4-(MeO)2] were prepd. using succinyl chloride as acylating reagent. Arom. 1,4-diketone I [R = 2,4,6-(MeO)3] was also prepd. by using succinic anhydride as acylating reagent. The first method could be used for the prepn. of arom. 1,4-diketones with the same arom. groups, and the second for the different arom. groups. [on SciFinder (R)]
