  o-Quinone Methides via Oxone-Mediated Benzofuran Oxidative Dearomatization and Their Intramolecular Cycloaddition with Carbonyl Groups: An Expeditious Construction of the Central Tetracyclic Core of Integrastatins, Epicoccolide A, and Epicocconigrone A

  摘要：

  The intramolecular cycloaddition of o-quinone methides (o-QMs) with a carbonyl group has been envisaged and executed successfully in the context of constructing the complex and rare [6,6,6,6]-tetracyclic core found in the integrastatins, epicoccolide A, and epicocconigrone A. These transient o-QMs were generated easily from the oxidative dearomatization of the corresponding C2-(aryl)benzofuran by employing Oxone in acetone-water at rt. The subsequent cydoaddition with the carbonyl (or conjugated olefin) present on the C2-aryl group was spontaneous.

  A direct oxidative C−H amidation of heteroarenes with sulfonamides via nitrogen‐centered radicals has been achieved. Nitrogen‐centered radicals are directly generated from oxidative cleavage of N−H bonds under visible‐light photoredox catalysis. Sulfonamides, which are easily accessed, are used as tunable nitrogen sources and bleach (aqueous NaClO solution) is used as the oxidant. A variety of heteroarenes

  日期：1993.4

  The reaction of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) with 6-methoxy-3-methylbenzofuran gave carbon–oxygen adduct. The reaction in less polar solvents such as benzene and CH2Cl2 proceeds faster than that in more polar solvents such as THF and dioxane. In contrast, the reaction of DDQ with indoles gave carbon–carbon adducts. This reaction proceeds rapidly with increasing solvent polarity.

  2,3-二氯-5,6-二氰基-对苯醌（DDQ）与6-甲氧基-3-甲基苯并呋喃反应生成碳-氧加合物。在极性较小的溶剂（如苯和 CH2Cl2）中的反应比在极性较大的溶剂（如 THF 和二恶烷）中进行得更快。相反，DDQ 与吲哚反应生成碳-碳加合物。该反应随着溶剂极性的增加而迅速进行。
