Modular Synthesis of gem-Difluorotetrahydrocarbazolone Scaffolds via Copper-Catalyzed Cascade Reaction of Bromodifluoroacetyl Indoles and Olefins
A novel and efficient modular synthesis of gem-difluorotetrahydrocarbazolone scaffolds via copper-catalyzed radical cascade cyclization of bromodifluoroacetyl indoles and olefins has been reported. This operationally simple protocol provides straightforward and practical access to a series of privileged gem-difluorotetrahydrocarbazolone scaffolds from readily available starting materials, with the feature of broad functional group tolerance and mild reaction conditions. Moreover, the method could be used for the late-stage functionalization of bioactive molecules, which opens up the possibility for practical applications.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
