Synthesis of Furoneoflavones Modified by Coumarin and (HET)Aroyl Substituents
Chem. Nat. Compd. 2021, 57 (1), 33-37
Furo[3,2-g]neoflavones and furo[2,3-h]neoflavones modified by coumarin and (het)aroyl substituents were synthesized via reactions of 7-hydroxy-6(8)-acetyl(formyl)neoflavones with substituted phenacyl bromides, 2-bromacetylbenzofuran, and 4-chloromethylcoumarins.
