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 b

Enantioenriched fluorinated heterocycles can be prepared through fluorocyclizations of prochiral indoles (see scheme; Ts=tosyl, Bn=benzyl, Boc=tert-butoxycarbonyl). More than twenty examples for this cascade fluorination-cyclization, which is catalyzed by cinchona alkaloids and employs N-fluorobenzenesulfonimide as the electrophilic fluorine source have been explored, and an unprecedented catalytic asymmetric difluorocyclization has also been identified.
