Photoinduced Pd-Catalyzed Dearomative 2,5-Difunctionalizition of Furans via Cascade C–C/C–O Bond Formation

We report an efficient and mild approach for radical dearomatization via photoinduced palladium-catalyzed reaction of three components (i.e., furans, alcohols, and bromoalkanes). In this strategy, various functionalized spiro-heterocycles were prepared from furans in one step via cascade C–C/C–O bond formation under redox neutral conditions
