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.

Novel pyrano[2,3-f]chromen-2,8-diones and pyrano[3,2-g]chromen-2,8-diones were prepared based on modified analogs of natural o-hydroxyformyl(acyl)neoflavonoids.
the synthesis of heterocyclic analogues of neoflavonoids, such as pyrazolyl-, isoxazolyl-, pyrimidinyl-substituted 4-phenyl-2H-chromen-2-ones and fused 4-phenyl-2H,6H-pyrano[3,2-g]chromene-2,6-diones and 4-phenyl-2H,10H-pyrano[2,3-f]chromene-2,10-diones, using the corresponding enaminoketones is described. heterocycles - 4-phenyl-2H-chromen-2-one - 2H-1-benzopyran-2-one - neoflavone - enamino ketone
