Article	Year
Synthesis of Coumestrol and Aureol. Journal of natural products, 2016, 10-28, Volume: 79, Issue:10 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. Topics: Catalysis; Copper; Coumarins; Coumestrol; Molecular Structure; Nuclear Magnetic Resonance, Biomolecular; Sesquiterpenes	2016
An efficient synthesis of coumestrol and coumestans by iodocyclization and Pd-catalyzed intramolecular lactonization. The Journal of organic chemistry, 2005, Nov-25, Volume: 70, Issue:24 [reaction: see text] The iodocyclization of acetoxy-containing 2-(1-alkynyl)anisoles and subsequent direct palladium-catalyzed carbonylation/lactonization provide an efficient route to naturally occurring coumestan and coumestrol, and their related analogues. Topics: Catalysis; Coumarins; Coumestrol; Cyclization; Iodine; Molecular Structure; Palladium	2005
