A novel series of benzamides with a hexahydro-1,4-diazepine or hexahydroazepine ring in the amine moiety were prepared, and their binding affinities for 5-HT3 and dopamine 4 receptors were evaluated. The R isomer of the 1-ethyl-4-methylhexahydro-1,4-diazepinylbenzamide (R)-22 had potent affinity for both receptors. The R-enantiomer of the corresponding 1-ethylhexahydroazepinylbenzamide 28 showed potent affinity for dopamine D2 receptors with reduced affinity for 5-HT3 receptors, while the S isomer was found to be a potent and selective 5-HT3 receptor antagonist.
A novel synthetic route to N6-methyl-L-lysine and N5-methyl-L-ornithine via N3-protected (S)-3-aminolactams1

(S)-3-Phthalimido- or (S)-3-tritylaminolactams, prepared from L-lysine and L-ornithine in two or three steps, are easily methylated at the endocyclic nitrogen atom by iodomethane/silver(I) oxide in dimethylformamide. Acid hydrolysis of the N-methylated lactams thus obtained affords N6-methyl-L-lysine and N5-methyl-L-ornithine hydrochlorides in high yield.
