, p. 107699 - 107707 (2016/11/29)
A sustainable procedure for the synthesis of N-heteroaryl amides directly from oxidative amidation of aldehydes catalyzed by heteropolyanion-based ionic liquids under microwave-promoted conditions has been reported. The transformation has proven to tolerate a wide range of aldehydes and amino heterocycles with different functional groups. Moderate to excellent yields, solvent-free media, operational simplicity and reusability of catalysts are the main highlights. Furthermore, the proposed N-directing dual-catalysis mechanistic pathway was briefly investigated in this report.
A one-pot copper catalyzed biomimetic route to n -heterocyclic amides from methyl ketones via oxidative c-c bond cleavage
Subramanian, Parthasarathi,Indu, Satrajit,Kaliappan, Krishna P.
supporting information, p. 6212 - 6215 (2015/01/09)
A direct one-pot Cu-catalyzed biomimetic oxidation of methyl ketones to pharmaceutically important N-heterocyclic amides is reported. The scope of the method is broad, scalable, and mild, and the reaction is tolerant with various acid, base sensitive functionalities with multiple heteroatoms and aryl halides. The extensive mechanistic studies suggest that this reaction follows the Luciferin-Luciferase-like pathway.
Studies on the Oxidation of the Azomethine Compounds with 3-Chloroperbenzoic Acid
Mlochowski, J.,Abdel-Latif, F. F.,Kubicz, E.,Said, S. B.
, p. 711 - 722 (2007/10/02)
Oxidation of the azomethine compounds such as Schiff bases and azines having several nucleophilic centers with 3-chloroperbenzoic acid (MCPBA) being an electrophilic oxidant was investigated.From azines 4, bisaldimines 5, 6, and pyridine derived monoaldimines 7, 8, having various substituents on the imine carbon and nitrogen atoms, the products such as nitrones 9, 15, bisoxaziridines 11, 12; acyldiimine 10 and amide 14 were obtained in high yields.The influence of the structure of substrate on the reaction result is discussed.Key words: aldimines, azines, nitrones, oxaziridines
