Abstract:Aminomethylation of substituted acetophenones with paraformaldehyde and piperidine hydrochloride yielded 4-substituted β-piperidinopropiophenones. Interaction of compounds I with the Grignard reagents in ether yielded 1-(4-substituted phenyl)-1-alkyl(aryl)-3-piperidinopropanols. The anti-inflammatory, analgesic, antipyretic, central m-cholinoblocking, and peripheral n-cholinoblocking actions of 1-(4-substituted phenyl)-1-alkyl(aryl)-3-piperidinopropanol hydrochlorides were studied. The study compounds were found to have marked central m-cholinoblocking and peripheral n-cholinoblocking activities. Only 1-(4-methoxyphenyl)-1-cyclohexyl-3-piperidinopropanol hydrochloride had anti-inflammatory activity.
