Abstract
Herein, we present an unprecedented electrochemical reductive cyclizative carboxylation of o-vinylphenyl isocyanides with carbon dioxide achieved without the use of metal catalysts. This protocol demonstrates a broad substrate scope and good functional group tolerance, facilitating the rapid assembly of 2-oxoindolin-3-acetic acids in good to high yields with excellent regioselectivity. Furthermore, these structural motifs may have potential applications in formal synthesis of bioactive 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.
