Ring the changes: Enyne acetals were easily converted into hydroazulene skeletons by a new and efficient metal-free route involving a Br?nsted acid promoted carbocyclization and a subsequent stereospecific Nazarov cyclization (see scheme). The versatility of this transformation also allowed assembly of interesting heteroaromatic tricyclic systems. Copyright
