as dipeptidyl peptidase IV inhibitors. As attractive synthons for these, N-protected (2S,4S)-4-fluoropyrrolidine-2-carbonyl fluorides were synthesized in high yield by double fluorination of N-protected (2S,4R)-4-hydroxyproline with 4-tert-butyl-2,6-dimethylphenylsulfur trifluoride (Fluolead). The 4-fluoropyrrolidine-2-carbonyl fluorides were converted to useful intermediates such as 4-fluoropyrrol
