Polystyrene-bound cinchona alkaloids: Application to enantioselective electrophilic fluorination of silyl enol ethers
A panoply of new polystyrene-bound cinchona alkaloids (PS-CA) has been prepared, and exploited for the design of unprecedented enantioselective electrophilic fluorinating agents. Compared to nonsupported [N-F]+ reagents, the polystyrene-bound N
