(+)-Aureol is a natural product that shows selective anticancer activity against certain strains of lung cancer and colon cancer. A key step in the biosynthesis of (+)-aureol (how nature makes the molecule) is believed to involve the conversion of carbocation A to carbocation B (Org. Lett. 2012, 14, 4710-4713). HO OH HO OH
