A direct catalytic asymmetric aldol reaction of aromatic aldehydes and thioamides is described. A soft Lewis acid/hard Bronsted base cooperative catalyst comprising (R,R)-Ph-BPE/[Cu(CH3CN)4]PF 6/Li(OC6H4-p-OMe) promoted the title reaction efficiently, triggered by in situ generation of the active thioamide enolate through a soft-soft interaction of Cu(I) and the thioamide. The aldol product was transformed into (R)-fluoxetine, an antidepressant agent.

Provided is an efficient method for the preparation of 3-aryloxy-3- arylpropylamines, their optical stereoisomers, and pharmaceutically acceptable salts thereof. The process allows for the isolation of 3-aryloxy-3- arylpropylamines in high yield and purity. The present invention further relates to a process for producing fluoxetine, tomoxetine, norfluoxetine, duloxetine, nisoxetine, and their optically enriched (R)- and (S)-enantiomers.

Methods and compositions are disclosed utilizing the pure S(+) isomer of fluoxetine which is a potent antidepressant and appetite suppressant substantially free of unwanted, adverse toxic or psychological effects, for the treatment of human depression. In addition, methods and compositions are disclosed utilizing the pure S(+) isomer of fluoxetine which is useful in treating migraine headaches, pain, in particular chronic pain, and obsessive-compulsive disorders. Further, methods and compositions for treating a condition alleviated or improved by inhibition of serotonin uptake in serotonergic neurons and platelets in a human using optically pure S(+) fluoxetine are disclosed.
