Synthesis of 1-arylpiperazyl-2-phenylcyclopropanes designed as antidopaminergic agents: Cyclopropane-based conformationally restricted analogs of haloperidol
A series of the cyclopropane-based conformationallyrestrictedanalogs of haloperidol were designed as potential antidopaminergic agents and were effectively synthesized using highly stereoselective Grignard reaction with tert-butanesulfinyl imines as the key step. Pharmacological evaluation of the compounds showed that the conformational restriction method can effectively work for improving the pharmacological
