Unexpected Reaction Of A-Aryl-N-(P-Phenylethyl) Nitrones With Chlorinating Agents
摘要:
The alpha-aryl-N-(beta-phenylethyl)nitrones when subjected to SO2Cl2/Et3N and NCS/NaOMe treatment independently, gave unexpectedly the corresponding amides. These procedures form an alternative route for the rearrangement of nitrones to amides.

to 4-amino-N-(1-phenylethyl)benzamide, 1, were prepared in a study on the relationship of structure to anticonvulsantactivity in this compound. Acylation and alkylation of the amino group of 1 resulted in almost total loss of anticonvulsantactivity. 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

An improved, fast, and efficient procedure for amide bondformation and peptide coupling is reported leading to the expected corresponding derivatives in good to excellent isolated yields ranging from 26 to 90%. The outcome of the reaction was also investigated in relation to the influence of different parameters such as the nature of the solvent, the temperature as well as the amine/carboxylic acid
