describes two new synthetic methods for the preparation of isoflavones following the Ni-catalysed domino arylation reactions of the vast range of ortho-hydroxyarylenaminones utilising aromatic bromides as well as carboxylic acids. The presented protocols tolerated significant variation of all coupling partners and enabled synthesis of isoflavone library of twenty-three representatives. This is the first

been synthesized as potential antitumor agents based on structural similarities to known flavones and isoflavones (quercetin and genistein respectively) and antitumor 2-phenylbenzothiazoles. Target compounds were synthesized using palladium-catalyzed coupling methodologies to construct the central aryl carbon-carbon single bond. The new isoflavone derivatives were tested for in vitro activity in human
