A series of 4-piperidylbenzimidazolinones, of formula I, has been synthesized. Selective syntheses of erythro and threo isomers of α-alkyl phenylethanolamines were investigated. Most members of the series have been shown to have antihypertensive effects in various animal models. Compounds 27 and 31 (threo isomers) showed the strongest hypotensive activities in the present screening series.
