Abstract

A new synthesis of stereochemically pure (L)-4-fluorotryptophan [i.e., (2S)-4-fluorotryptophan] in seven steps from 4-fluoroindole is described. A key reaction in the synthetic strategy is a diastereoselective alkylation of the Schollkopf chiral auxiliary with a fluorinated electrophile. All reaction steps are efficient and proceed in at least 80% yield.
