Microwave-assisted heteropolyanion-based ionic liquid promoted sustainable protocol to N-heteroaryl amides via N-directing dual catalyzed oxidative amidation of aldehydes?
RSC Advances Pub Date: 2016-11-07 DOI: 10.1039/C6RA20961K
Abstract
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.
