Palladium-Catalyzed Cascade Reaction of Indoles with α,α-Difluoro-β,γ-Unsaturated Ketones: One-Step Access to 2-Fluorocarbazoles
{{output}}
A practical synthesis of pharmacologically and materially relevant fluorinated carbazoles is highly desirable yet remains challenging. Herein, we report an efficient route to 2-fluorocarbazoles via a Pd(0)/Cu(I)-cocatalyzed tandem reaction between readily avai... ...
