N,N-Dimethylaminophenyl moiety is a common fragment in medicinal chemistry as several pharmaceuticals bearing this privileged motif are on the market and under clinical evaluation. Oxidative N-demethylation is generally regarded as the major metabolic pathway. However, pharmacokinetics, metabolites studies as well as the further structural modification are precluded by the impracticality of chemical synthesis. Here we report that acetic acid can significantly accelerate visible-light photoredox catalyzed N-demethylation of N,N-dimethylaminophenyl derivatives. This approach is easy for large scale reaction and even for potential industrial manufacture. (Figure presented.).

Ligand-assisted copper-catalyzed reaction of aldoximes with aryl halides is described for the regioselective synthesis of N-aryl amides. This protocol is simple and compatible with a wide range of functional groups attached to the aryl ring of the halides as well as aldoximes. Copyright

p-Dimethylaminobenzanilides with a para or meta substituent at the amido anilino moiety were designed to generate a series of dual fluorescent molecules of variable electron acceptors. Ab initio calculations indicated that the anilino substitution did not
Synthesis and Anticonvulsant Activity of Analogues of 4-Amino-N-(1-phenylethyl)benzamide

, p. 1214 - 1218 (2007/10/02)
A group of amides and amines related to 4-amino-N-(1-phenylethyl)benzamide, 1, were prepared in a study on the relationship of structure to anticonvulsant activity in this compound. Acylation and alkylation of the amino group of 1 resulted in almost total loss of anticonvulsant activity. Insertion of a methylene between the 4-amino group and the aromatic ring of 1 produced a slight increase in anticonvulsant potency and a significant increase in toxicity. Hydride reduction of the amide carbonyl in 1 also yielded compounds having a slightly lower ED50 against convulsions induced by electroshock and a much lower TD50 in the rotorod assay. Modification of the 1-phenylethyl group of 1 also decreased anticonvulsant potency.
