Simple cyclization: A novel method has been developed for the highly regio‐ and stereoselectivesynthesis of nine‐ to twelve‐membered cycliccompounds by a Pd0‐catalyzed cyclizationreaction of allenes with a carbon or nitrogen nucleophilicfunctionality. Oxidative addition and carbopalladation gave anti‐π‐allyl palladium intermediates, then an exclusive intramolecular nucleophilic attack at the terminal
