Polystyrene-bound cinchona alkaloids: Application to enantioselective electrophilic fluorination of silyl enol ethers

Thierry, Baptiste,Audouard, Christophe,Plaquevent, Jean-Christophe,Cahard, Dominique

, p. 856 - 860 (2004)

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
