Aldot condensations between a ketone acting as methylene compound and an aldehyde are termed C laiscn-Schmidt condensations [9]. Therefore. Claisen-Schmidt condensations between acetophenone and bcn/aldchyde derivatives allow u.p-unsaturated ketones called chalconcs (Figure 14) 1110, 182, 256-258]. Chalcones are flavonoids of numerous applications as pesticides, phoioproiector in plastics, solar creams, food additives and many biological activities [Pg.98]
