The formal (3+2) cycloaddition between terminal allenes and aryl or styryl gold(I) carbenes generated by a retro‐Buchner reaction of 7‐substituted 1,3,5‐cycloheptatrienes led to indenes and cyclopentadienes, respectively. These cycloaddition processes have been applied to the construction of the carbon skeleton of the cycloaurenones and the dysiherbols as well as to the total synthesis of (±)‐laurokamurene B.
