—— | 3-(4-chlorophenyl)-3-butenoic acid | 81187-88-4 | C10H9ClO2 | 196.633 |
(Z)- and (E)-4-Amino-3-(4-chlorophenyl)but-2-enoic acids have been synthesized from 4-chloroacetophenone as conformationally restricted analogues of baclofen. The corresponding unsaturated lactam (4) has been catalytically reduced and hydrolysed to baclofen to demonstrate the suitability of (4) as a precursor for radiolabelled baclofen of high specific activity.
