Cesium carbonate promoted aerobic oxidation of arylacetamides: an efficient access to N-substituted α-keto amides
摘要:
A novel cesium carbonate promoted aerobic oxidation reaction to prepare N-substituted alpha-keto amides in the presence of catalytic amount of tetra-n-butylammonium bromide was described. This reaction provides a very simple and convenient route from easily available arylacetamides in good to high yields. (c) 2007 Elsevier Ltd. All rights reserved.

(λ=210 nm) promoted procedure proceeding in aqueous media at room temperature using ambient air as the oxidant for efficient synthesis of an array of α‐ketoamides of all types using a non‐metal catalyst N‐iodosuccinimide with a loading of 20 mol%. With UV, oxygen in the air was efficiently utilized as the green oxidant, some control experiments were carried out and a plausible mechanism was proposed

carbonylation protocol usingheterogeneous Pd0 nanoparticles supported on the metal–organicframeworks (MOFs) MIL‐88B‐NH2 (Fe/Cr). The synthesis of a vast array of carbonyls, which includes amides, esters, carboxylic acids, and α‐ketoamides, was achieved through mono‐ and dicarbonylation reactions. The selectivity could be controlled simply by tuning the reaction conditions. Superior activity and selectivity
An effective green synthesis of α-ketoamides was developed for the first time in water via gold nanoparticles (AuNPs) catalyzedaerobicoxidative cross-dehydrogenative coupling of secondary amines with phenylglyoxals with a broad substrate scope.
Room temperature copper-catalyzed oxidative amidation of terminal alkynes for the synthesis of α-ketoamides using O-benzoyl hydroxylamines as aminating reagent and oxidant
A novel and convenient copper-catalyzed oxidative amidation for the synthesis of α-ketoamides has been successfully developed, which uses easily available O-benzoyl hydroxylamines as aminating reagent and oxidant. The reaction proceeds smoothly at room temperature and is compatible with a range of substrates to give the desired products in moderate to good yields.
