Abstract
(Hetero)arylated bicyclo[1.1.1]pentanes (BCPs) are important for the construction of complex druglike target molecules. Herein, we developed a method for light-induced, Cs2CO3-promoted homolytic cleavage of pyridinium C-N bonds for generating alkyl radicals from amino acid-derived Katritzky salts and use of the radicals for functionalization of [1.1.1]propellane to rapidly generate (hetero)arylated BCPs. The method features excellent functional group tolerance and a broad substrate scope and can be used to functionalize structurally complex natural products.
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.
