New flavones by a novel synthetic route
Sandulache, Angela,Cascaval, Alexandru,Toniutti, Nicoletta,Giumanini, Angelo G.
, p. 9813 - 9822 (1997)
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.
