Trans-diastereoselectivity and enantioselectivity inthe formation of thomasidioic acid was observed. Computational methods show that theenantioselectivity is controlled by the ¦Â-¦Â oxidative coupling step, while thediastereoselectivity is controlled by the stability of the reactive conformation of theintermediate quinomethide. %K Diastereoselection %K enantioselection %K lignans %K horseradish peroxidase %K oxidative %U http://www.mdpi.com/1420-3049/13/1/129
