pyridines provides access to chiral pyridines via an opera- tionally simple protocol that obviates the need for prefunc- tionalization or preactivation of the substrate. The alkylation is accomplished using chiral lithium amides as non-covalent stereodirecting auxiliaries. Crystallographic and solution NMR studies provide insight into the structure of well- defined chiral aggregates in which a lithium

The anticonvulsant effect of a series of 6-alkyl-N,N-disubstituted-2-pyridinamines is described. An investigation was carried out to optimize the anticonvulsant activity and reduce behavioral side effects in this series. Three compounds (7, 8, 10; Table I) were selected from initial screening for a more complete pharmacological evaluation. While each of these compounds was a potent anticonvulsant agent with ED50 values from 5 to 10 mg/kg, the activity was accompanied by significant behavioral side effects including decreased spontaneous locomotion, ataxia, and ptosis.
