Abstract

A new, high yield regioselective reaction affording racemic and enantiomeric 1,2-dimethyl-3-[2-(6-substituted naphthyl)]-2H,5H-pyrrolines is reported. Compounds were provided by dehydration of the corresponding 1,2-dimethyl-3-[2-(6-substitutednaphthyl)]-3-hydroxypyrrolidines under microwave irradiation and solvent-free conditions. Pharmacological properties of enantiomeric compounds are also described; the analgesic activity was investigated by the hot plate test. A conformational analysis of the compounds was carried out by molecular modeling techniques with the aim to get information about the fitting to known analgesic pharmacophore models.
