  Tandem Cyclization of α-Cyano α-Alkynyl Aryl Ketones Induced by tert-Butyl Hydroperoxide and Tetrabutylammonium Iodide

  摘要：

  The radical cascade protocol of the alpha-cyano alpha-TMS/aryl-capped alkynyl aryl ketones promoted by tert-butyl hydroperoxide under catalysis with tetrabutylammonium iodide in refluxing benzene has been developed, leading to the construction of a variety of highly functionalized [6,6,5] tricyclic frameworks in an efficient manner.

  cyclopenta‐[b]naphthalene derivatives via the palladium(0)/copper(I)‐catalyzed tandem cyclization of aryl 1‐cyanoalk‐5‐ynyl ketone systems in an extremely efficient manner. The key operation lies in the copper(I)‐catalyzed aerobic oxidation, which allows for activation of two successive intramolecular cycloadditions immediately after the Sonogashira coupling reaction has occurred.

  我们已经开发出一种新的通用方法，可通过钯（0）/铜（I）催化的芳基1-氰基烷基-5-炔基的串联环化反应来构建各种苯并[ b ]芴和环戊[ b ]萘衍生物。酮系统的效率极高。关键操作在于铜（I）催化的好氧氧化，该反应可在Sonogashira偶联反应发生后立即激活两个连续的分子内环加成反应。
