The first ever enantiopure N-fluoro quaternary ammonium salt of cinchonidine (F-CD-BF 4 ) was prepared as an enantioselective fluorinating agent. A one-step transfer-fluorination of the quinuclidine moiety with Selectfluor ® gave the [N F] + reagent. The X-ray structure of F-CD-BF 4 was determined,
