Novel amino‐acid‐derived phthalazine reagents have been designed and synthesized for the enantioselective fluorocyclizations of prochiral indoles. The scope of reaction is evidenced by 28 examples of fluorinated furoindole and pyrroloindole heterocycles bearing various functionalities with up to 99% ee. The resulting enantioenriched fluorinated products are found to be potent AChE inhibitors. Advantages
