title: Medium-sized carbocycles by a zirconocene-catalyzed tandem formal ring expansion-magnesation reaction of alkenyl-substituted cyclic enol ethers.
abstract: A new regio- and stereoselective zirconocene-catalyzed reaction for the synthesis of medium-sized rings is described. The global reaction supposes a formal ring expansion of a cyclic enol ether to give a functionalized carbocycle.
