A highly enantioselective fluorination of indanone-2-carboxylates catalyzed by a polystyrene-supported diphenylamine-linked bis(oxazoline) (PS-box)-Cu(OTf)2 complex has been developed in a continuous flow system. The supported complex exhibited extremely efficient catalytic performance with high activity, affording the corresponding products in excellent yields (up to 99% yield) with excellent enantioselectivities (up to 99% ee) and more than 4000 turnover number (TON).
