Pd-catalyzed enantioselective reductive Heck reaction of mono-fluoro, gem-difluoro, and trifluoromethyl tethered-alkenes.

Herein, we present an enantioselective, fluorine-retentive Pd-catalyzed reductive Heck cyclization reaction of fluorinated alkenes, enabling the synthesis of all-carbon quaternary 3,3-disubstituted fluoroalkyl-tethered oxindoles. Control experiments and DFT studies have provided insights into the reaction mechanism and stereochemical induction.
