Abstract
Abstract Seven-membered ring annulation is achieved by an intramolecular Michael reaction catalyzed by iron(III) chloride hexahydrate. Reaction conditions are mild and non-basic, and chemo- and stereoselectivity is excellent. Contrastingly, this method fails for a 17-membered ring annulation.
