A series of chrysin derivatives were prepared from 2-hydroxyacetophenone, 2,4-dihydroxyacetophenone, 2,4,6- trihydroxy- acetophenone, using modified Baker-Venkataraman transformation. Their anticancer activities in vitro were evaluated by the standard MTT method. The results of biological test showed that some of chrysin derivatives showed stronger anticancer activity than 5-fluorouracil.

The total synthesis of furoflavones closely related to the natural product cissampeloflavone was achieved following different pathways. The conjugate addition of an iodoflavone to an ynone followed by an intramolecular Heck cyclization gave the best results, leading to the first synthetic chalcone–flavone dimer ever described.

Abstract Fronds of various ferns in the genus Notholaena produce an exudate which consists mostly of flavonoid aglycones. In some species we found small amounts of two dibenzoylmethanes or β-diketones. These have been identified by spectroscopic methods. Both, 2′,β,4-trihydroxy-4′,6′-dimethoxychalcone and 2′,β-dihydroxy-4′,6′,4-trimethoxychalcone, are novel natural products. The structures have been
