2-Fluoroalkyl-substituted indole derivatives were simply prepared via the Grignard cyclization reaction (GCR) of corresponding fluorinated N-aryl imidoyl chlorides in good yields. This approach provides a novel and facile access to the biologically important 2-fluoroalkylindole derivatives.
Fluorinated N-[2-(haloalkyl)phenyl]imidoyl chloride, a key intermediate for the synthesis of 2-fluoroalkyl substituted indole derivatives via Grignard cyclization process
N-[2-(haloalkyl)phenyl]imidoylchloride, which was readily available from the corresponding anilines by using Uneyama's one-pot synthesis of fluorinated imidoylchloride, was found to be a key intermediate for the facile synthesis of 2-fluoroalkyl substituted indole derivatives via the Grignard cyclization process. The bromination of 3-methyl group of 3-methyl-2-trifluoromethyl indole with NBS/CCl4 led

an organophotocatalytic direct difluoromethylation of heterocycles using O2 as a green oxidant. The C-H oxidative difluoromethylation obviates the need for pre-functionalization of the substrates, metals and additives. The operationally straightforward method enriches the efficient synthesis of many difluoromethylated heterocycles in moderate to excellent yields. The direct difluoromethylation of pharmaceutical
