General description

Influence of solvents and temperature on the yield and enantioselectivity of the phenylation of 3′-chloropropiophenone has been investigated.

Application

3′-Chloropropiophenone can be used as a reactant to synthesize:
  • (S)-3-chloro-1-phenylpropanol via bio-catalyzed asymmetric reduction method.
  • 1-(3-Chlorophenyl)-1-phenyl-1-propanol by phenylation with diphenylzinc in the presence of dihydroxy bis(sulfonamide) ligand.
  • (S)-Dapoxetine, a selective serotonin reuptake inhibitor.

[reaction: see text] The catalytic asymmetric addition of phenyl groups from diphenylzinc to ketones is reported. The catalyst, generated from a dihydroxy bis(sulfonamide) ligand and titanium tetraisopropoxide, gives good to excellent enantioselectivities with a range of substrates.
