New flavones by a novel synthetic route

Twelve new flavones (3) were prepared by the reaction of 2-hydroxy-α- bromoacetophenones (1) with piperidine or morpholine aminals of benzaldeydes (2) in refluxing methanol. The products (3) were fully characterised by 1H NMR and IR spectroscopy and MS spectrometry.

Reaction of 2'-Hydroxychalcone Dibromides with Me2SO

2'-Hydroxychalcone dibromides on treatment with Me2SO gave 2'-hydroxychalcone, 2'-hydroxy-3'- or 2'-hydroxy-5'-bromochalcone, flavone, monobrominated flavone, 6,8-dibromoflavone, 3-bromoflavone, and 3-, 6-, or 8-dibromoflavone.
