The key step is a biomimetic ring expansion of a highly stabilized benzylic carbocation, which generates the seven-membered ring and the benzofuran of the natural product in a single cascade reaction.en© 2010 American Chemical SocietyTerpenesDiterpenesMolecular ConformationStereoisomerismJournal article002011255610.1021/ol100756z0002775310000572-s2.0-7795236757027835George, J.
