Initial examples of a Rh(I)-catalyzed [2+2+1] reaction of diene-enes and CO are described. This method allows for the facile, efficient, and diastereoselective construction of a variety of alkenyl cyclopentanones in good to excellent yields. Control studies show that the diene moiety is required for this process as bis-enes do not give the [2+2+1] products under the same conditions.
描述了 Rh(I) 催化的二烯-烯和 CO 的 [2+2+1] 反应的初始实例。这种方法允许以良好到极好的产率轻松、有效和非对映选择性地构建各种烯基环戊酮。对照研究表明,该过程需要二烯部分,因为在相同条件下双烯不会产生 [2+2+1] 产物。
