C_(Ar)-Br bond cleavage via cooperative EnT/NHC catalysis: mild access to indolines

引用

Science China Chemistry 2024年第3期67卷 922-927页

作者： Yi-Xiong Dong cao-bo Li Ming-Lei Jin Zhong-Hua Gao Song Ye Beijing National Laboratory for Molecular Sciences CAS Key Laboratory of Molecular Recognition and FunctionCAS Research/Education Center for Excellence in Molecular SciencesInstitute of ChemistryChinese Academy of SciencesBeijing 100190China University of Chinese Academy of Sciences Beijing 100049China

The cooperative visible-light mediated and NHC-catalyzed dearomative arylation-acylation of N-(2-bromobenzoyl)indoles with aldehydes was developed, affording the corresponding highly functionalized polycyclic indolines in moderate to good yields with exclusive diastereoselectivities. Mechanism investigations support the activation of CAr-Br bond via visible-light mediated energy transfer(EnT) and the following single-electron-transfer(SET) with Breslow intermediate under NHC catalysis to give key aryl radical and ketyl radical. This protocol demonstrates the cleavage of CAr-Br bond under mild cooperative EnT/NHC catalysis.

智力成果权利证成主流学说的演进历程,说明了意志论和利益论的解释力与影响力,但也呈现出知识产权领域对现代权利理论的更新调整缺乏跟进的缺憾。权利程序理论实现了从实体问题向程序问题的范式转换,建构了主体平等参与、利益评价及规范程序构成的基本模式,但该模式还存在对平等参与的关注局限于形式公平、利益评价仅以个人利益为对象和规范程序只针对立法过程等缺陷。将实质公平的考量、制度利益与公共利益的铺陈以及司法在规范程序中的促进作用,纳入权利程序理论,将补足其存在的理论盲点与逻辑缺陷。以此为据,可归纳出智力成果权利化的程序难题:参与主体的两分结构与修辞表达、利益内涵的多重属性及外部冲突、法律移植的历史局限与文化碰撞。相应的破解之道在于:参与主体的全面罗列与类型界分、利益内涵的澄清与义务履行的实现以及通过疑难案件的裁判实现立法与司法的互动。
