A novel series of N-(benzoylalkyl)imidazoles and N-(omega-phenyl-omega-hydroxyalkyl)imidazoles was synthesized and evaluated for anticonvulsant activity in mice against maximal electroshock induced seizures. Some of the compounds showed an activity comparable to or better than phenytoin and phenobarbital. The N-[beta-[4-(beta-phenylethyl)phenyl]-beta-hydroxyethyl]imidazole (38) was selected for further studies; preclinical toxicology and additional efficacy evaluations are in progress. Structure-activity relationships are discussed.

Chiral β-heteroaryl amino alcohols are key fragments of many bioactive compounds and antibiotics, and the development of efficient synthetic methods for these compounds is of great value. The highlyenantioselective hydrogenation of α-N-heteroaryl ketones was realized with a ruthenium-diphosphine–diamine catalyst, providing the corresponding chiral β-heteroaryl amino alcohols with up to 99% yield and
