  A variety of 5,4′-disubstituted flavones, which are anticipated to be androgen receptor antagonists to treat diseases mediated by the androgen receptor, were synthesized. It was found that an intramolecular ipso-substitution reaction via cesium enolate using 2-fluoro-6-hydroxyacetophenone and various benzoyl chlorides was effective in the preparation of 5-hydroxy-4′-alkylflavones.

  A number of 4'-substituted (R = H, Me, Cl, F) flavone derivatives is synthesized from 2-hydroxyacetophenones using the modified Baker–Venkataraman reaction. Compound [3-(4-fluorobenzoyl)-5- hydroxy-4'-fluoroflavone] was synthesized for the first time with the yield of 12%. Antiproliferative assays indicate that the synthesized flavones with F substituent at the 4' position demonstrate higher activity

  The invention relates to a process for the preparation of flavone derivatives in which a 2-hydroxyacetophenone compound is metallated using a lithium compound at low temperatures and subsequently reacted with a keto compound, and where the ratio of the molar equivalents of lithium compound to the 2-hydroxyacetophenone compound functional groups to be metallated is from 1 to 1.2. The resultant &bgr;-diketone compound is subsequently cyclised with warming in an acidic medium.

  The synthesis and mass spectra of three 3-aroyl-5-hydroxyflavones are reported. The interpretation of the mechanistic pathways for the fragmentation of the metastable molecular ions of these compounds was achieved through the analysis of their mass-analysed ion kinetic energy (MIKE) spectra and of the B-2/E spectra of a few fragment ions. Labelling of the hydroxyl proton with deuterium and the analysis of the MIKE spectra of a model compound with chlorine atoms in the 2',6'- and 2 '',6 ''-positions led to a mechanism for the losses of OH. and HCO. which involves hydrogen migration from the 2 ''- or 6 ''-position to the 4-carbonyl oxygen atom. A mechanism for the loss of a neutral molecule of anisole from the molecular ion of the 3-aroyl-5-hydroxyflavone with a methoxyl group in the 4'- and 4 ''-positions is also suggested. For the flavones with hydrogen or chlorine substituents at these positions, loss of a phenyl (or chlorophenyl) radical occurs instead. (C) 1997 by John Wiley & Sons, Ltd.
