Isoflavone derivatives were synthesized via intramolecular cyclization of 3-(2-bromophenyl)-3oxopropanal derivatives, using CuI as the catalyst, 2-picolinic acid (ΒΌ pyridine-2-carboxylic acid) as the ligand, K 2 CO 3 as the base, and DMF as the solvent, in up to 96% yield. The synthesis is functiona
