experimental part, p. 1688 - 1694 (2010/10/19)
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.

An efficient, practical asymmetric synthesis of (R)-norfluoxetine 1 and (R)-fluoxetine 2 has been achieved. The synthetic strategy features a Sharpless asymmetric dihydroxylation (SAD) route to the common building block 1,3-amino alcohol 9, from which (R)-norfluoxetine, (R)-fluoxetine and other related analogs can be synthesized.
