C(sp3)–H bond functionalization and C(sp3)–C(sp3) bond cleavage are very challenging transformations in chemistry. Herein, we report a mild and green methodology for the construction of N-(pyridine-2-yl)amides via tandem C(sp3)–H activation/C–C bond cleavage of alkylarenes. Various N-heterocyclic amides were directly synthesized from alkylarenes in water in moderate to good yields.

, 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.

The first metal free report on the amidation of aldehydes with aminopyridines was accomplished using simple aqueous hydrogen peroxide (aq. H2O2) as the oxidant. No catalysts or additives were needed for this transformation and the reaction proceeded in water, an environmentally benign reaction medium. Green oxidant and reaction conditions, and the ability to construct diverse N-(pyridin-2-yl)benzamide by this elegant method render it a practical alternative for the synthesis of these amides.

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.
