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.
7-取代的1,3,5-环庚三烯的逆布赫纳反应产生的末端丙二烯和芳基或苯乙烯基金(I)卡宾之间的正式(3+2)环加成分别生成茚和环戊二烯。这些环加成过程已应用于环aurenones和dysiherbols的碳骨架的构建以及(±)-laurokamurene B的全合成。
