Fluoxetine synthesis: US4314081A

Fluoxetine is marketed as a racemate. Both of its enantiomers display similar activity both in vitro (Ki, (R)-(+)-enantiomer is 21 nM and Ki, (S)-(-)- enantiomer is 33 nM) and in vivo. However, it is (S)-fluoxetine that is the predominant therapeutic enantiomer since it is eliminated more slowly that the (R)-enantiomer.
