A comparison of enaminones from various unsubstituted and p-substituted benzamides to the analogous benzylamines has been undertaken with the aim of elucidating the essential structural parameters necessary for anticonvulsantactivity. Initial studies on methyl 4-N-(benzylamino)-6-methyl-2-oxocyclohex-3-en-1-oate, 3a, 3-N-(benzylamino)cyclohex-2-en-1-one, 3p, and 5,5-dimethyl-3-N-(benzylamino)-cyclohex-2-en-1-one

cascade approach for the synthesis of meta‐N,N‐diarylaminophenols (DAAP) starting from exocyclic β‐enaminones has been developed. The feasibility of the process is rationalized by the suitable molecular geometry of β‐enaminones for tandem N‐arylative α‐iodination and aromatization under milder basic conditions. Furthermore, the developed strategy has been extended to the synthesis of meta‐N‐benzyl‐N‐arylaminophenols

The mechanism of anticonvulsant action was evaluated for the benzylamino enaminones. The most potent enaminone in this series was the unsubstituted benzylamine analog (30; methyl 4-benzylamino-6-methyl-2-oxocyclohex-3-en-1-oate) which had an oral effective dose (EDSO) in rats of 27 mg/kg against maximal electroshock seizures, and a concentration 10-fold less than this dose depressed excitatory synaptic transmission, and action potential firing in the rat brain in vitro.
