efficient route for the synthesis of (Z)- and (E)-3-styryl-4-quinolones is described. Wittig reaction of 4-(chlo- roquinoline- and quinolone)-3-carbaldehydes with benzylic ylides is the key transformation for this synthetic route. The (Z)-1-methyl- 3-styryl-4-quinolone is obtained with high diastereoselectivity from the reaction of 1-methyl-4-quinolone-3-carbaldehyde; while (E)-3- styryl-4-quinolone
