Asymmetric dearomatizing fluorocyclization of indole derivatives was investigated using a dicarboxylate phase-transfer catalyst. This reaction proceeds under mild reaction conditions to provide fluoropyrroloindoline derivatives in a highly enantioselective manner. Various substitution patterns on the indole ring are well tolerated. To facilitate the reaction and ensure reproducibility, the addition of water is essential, and its possible role is discussed.

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.

Substituted indole-3-acetic acid (IAA) derivatives, plant auxins with potential for use as prodrugs in enzyme-prodrug directed cancer therapies, were oxidised with horseradish peroxidase (HRP) and toxicity against V79 Chinese hamster lung fibroblasts was determined. Rate constants for oxidation by HRP compound I were also measured. Halogenated IAAs were found to be the most cytotoxic, with typical surviving fractions of -3 after incubation for 2 h with 100 μM prodrug and HRP.
