Abstract The use of gem ‐difluorinated cyclopropanes ( gem ‐DFCPs) as fluoroallyl surrogates under transition‐metal catalysis has drawn considerable attention recently but such reactions are restricted to producing achiral or racemic mono‐fluoroalkenes. Herein, we report the first enantioselective allylation of indoles under rhodium catalysis with gem ‐DFCPs. This reaction shows exceptional branched regioselectivity towards rhodium catalysis with gem ‐DFCPs, which provides an efficient route to enantioenriched fluoroallylated indoles with wide substrate scope and good functional group tolerance.
