Ethyl α-bromo-2,4- or -3,4-dihalogenophenylacetates (ABr), where halogen = F or Cl, are prepared and electrolysed on reticulated vitreous carbon (RVC) in dimethylformamide containing Et4NClO4 (0.1 mol dm-3).Potentiostatic reduction at E = -1.6 to -1.8 V versus SCE furnishes the corresponding racemic and meso succinates (AA) (13)-(16).Monoesters AH (5)-(8) are also isolated.An excess of racemic isomer is observed for (14), (15), and (16).Voltammetric experiments show practically no difference between the reduction potentials of the isomeric compounds.Diastereoisomers can be distinguished by NMR spectroscopy, allowing diastereoisomeric excess (de) to be evaluated before isolation of the single products.A mechanism involving radical intermediates A* cannot be excluded.On this basis, the des can be explained by assuming different geometries for A* when the phenyl group bears different substituents.

A series of 1-aryl-3-azabicyclohexanes was synthesized by hydride reduction of 1-arylcyclopropanedicarboximides.Hydroxyphenyl analogues 20, 22, and 24 were prepared by EtSNa-DMF ether cleavage of the corresponding methoxyphenyl analogues 2m, 2n, and 23, respectively, with the secondary amines 20 and 22 going through the N-formyl intermediates 19 and 21.The p-ethoxy analogue 26 was obtained by O-ethylation of 19, followed by base hydrolysis of the amide 25.The greatest analgesic potency in mouse writhing and rat paw-pain assays was observed for para-substituted compounds.Bicifadine, 1-(4-methylphenyl)-3-azabicyclohexane (2b), was the most potent member of the series and is presently undergoing clinical trials in man.Analgesic activity of 2b is limited to the (+) enantiomer 2v, which has the 1R,5S absolute configuration as determined by single-crystal X-ray analysis.The N-methyl analogue (27d) of 2b showed significant analgesic potency, whereas the N-allyl (27a), N-(cyclopropylmethyl) (27b), and N-(n-hexyl) (27c) analogues were inactive.Bicifadine (2b) showed a nonnarcotic profile different from analogous azabicycloalkane and 3-phenylpyrrolidine analgesics.
