A mild and facile two-step strategy has been developed for the synthesis of fluorinated 3,4-dihydropyrimido-[1,6-a]-indol-1(2H)-ones through Cp*Rh(III)-catalyzed C-H 3,3-difluoroallylation and N-iodosuccinimide (NIS)-mediated cyclization. This strategy featured broad synthetic generality, unique versatility and high efficiency, which provided a potential tool for the construction of fluorine-containing heterocycles for drug discovery.
