Abstract: The synthesis of particular cyclopropane-tethered 1,5-enynes, namely 6-alkynyl-4-alkylidenebicyclo[3.1.0]hex-2-enes, enabled the discovery of unprecedented gold-catalyzed rearrangment to indenes. A computational study of the mechanism of this profound skeleton rearrangement is also disclosed. read more here.
