Visible-Light-Promoted Formal [4 + 3] Radical Annulation of Vinyldiazos: Access to Fluorinated Cyclohepta[ b ]indoles

Abstract Cyclohepta[b]indoles are important nitrogen-containing heterocycles, yet their efficient synthesis remains challenging. Herein, we report a visible-light-promoted formal [4 + 3] cyclization of 3-difluorobromoacetylindoles with vinyldiazos through a photoredox cascade rad...
