A total synthesis of coumestrol (1) and aureol (2) is described. The Perkin condensation of 2-bromo-4-hydroxylphenylacetic acid (6) and o-hydroxybenzaldehydes (7) gave the corresponding 2′-bromo-3-arylcoumarins (9). A copper-catalyzed consecutive hydroxylation and aerobic oxidative coupling of 9 under microwave conditions facilitated the total synthesis of 1 and 2, respectively, with spectroscopic data highly similar to those of natural products.
