been synthesized in a short and concise manner employing readily available 4-hydroxyquinolin-2(1H)-ones as intermediates. Keysteps in the synthesis include the derivatization of the quinolin-2(1H)-one cores usingpalladium-catalyzed Suzuki and Heck reactions, installing the 4-aryl and 3-alkenyl substituents. All synthetic transformations (six steps) required for the synthesis of the desired target
