Diversification of α-ketoamides: Via transamidation reactions with alkyl and benzyl amines at room temperature

A wide range of N-tosyl α-ketoamides underwent transamidation with various alkyl amines in the absence of a catalyst, base, or additive. On the other hand, transamidation in N-Boc α-ketoamides was achieved in the presence of Cs2CO3. The reactions proceede

Rapid assembly of α-ketoamides through a decarboxylative strategy of isocyanates with α-oxocarboxylic acids under mild conditions

A simple and practical method for α-ketoamide synthesis via a decarboxylative strategy of isocyanates with α-oxocarboxylic acids is described. The reaction proceeds at room temperature under mild conditions without an oxidant or an additive, showing good substrate scope and functional compatibility. Moreover, the applicability of this method was further demonstrated by the synthesis of various bioactive molecules and different application examples through a two-step one-pot operation.

Synthesis of aliphatic α-ketoamides from α-substituted methyl ketones: Via a Cu-catalyzed aerobic oxidative amidation

α-Ketoamides are an important key functional group and have been used as versatile and valuable intermediates and synthons in a variety of functional group transformations. Synthetic methods for making aryl α-ketoamides as drug candidates have been greatly improved through metal-catalyzed aerobic oxidative amidations. However, the preparation of alkyl α-ketoamides through metal-catalyzed aerobic oxidative amidations has not been reported because generating α-ketoamides from aliphatic ketones with two α-carbons theoretically provides two distinct α-ketoamides. Our strategy is to activate the α-carbon by introducing an N-substituent at one of the two α-positions. The key to this strategy is how heterocyclic compounds such as triazoles and imidazoles affect the selectivity of the synthesis of the alkyl α-ketoamides. From this basic concept, and by optimizing the reaction and elucidating the mechanism of the synthesis of aryl α-ketoamides via a copper-catalyzed aerobic oxidative amidation, we prepared fourteen aliphatic α-ketoamides in high yields (48-84%). This journal is

Electrochemical Synthesis of α-Ketoamides under Catalyst-, Oxidant-, and Electrolyte-Free Conditions

A catalyst-, oxidant-, electrolyte-free method for the preparation of α-ketoamides through the direct electrochemical amidation of α-ketoaldehydes and amines with innocuous hydrogen as the sole byproduct at ambient temperature was developed. The present reaction features clean and mild conditions, excellent functional-group tolerance, and high atom economy and scalability, enabling facile applications in pharmaceutical chemistry.

One pot synthesis of α-ketoamides from ethylarenes and amines: a metal free difunctionalization strategy

One-pot and metal free synthesis of α-ketoamides has been described through in situ generation of aryl ketones from easily available ethylarenes followed by amidation with various amines. This multiple oxidation protocol involves catalytic I2-pyridine-TBHP (t-butyl hydroperoxide) mediated oxidative benzylic carbonylation and sequential NaI-TBHP mediated oxidative amidation without using any solvent.

A palladium-bisoxazoline supported catalyst for selective synthesis of aryl esters and aryl amides: Via carbonylative coupling reactions

The catalytic synthesis of aryl esters and amides has been successfully achieved in the presence of the efficient palladium-bisoxazoline supported on Merrifield's resin (Pd-BOX-M). The palladium heterogeneous catalyst was prepared and characterized using various spectroscopic techniques. A bisoxazoline ligand having a suitable functional group (BOX-OH) was first synthesized, characterized, chemically supported on Merrifield's resin, and finally coordinated to palladium(ii) chloride. The catalytic activity and the recycling ability of the new palladium supported catalyst have been investigated in the alkoxycarbonylation and aminocarbonylation of various aryl iodides using different alkyl and aromatic alcohols and amines as nucleophiles. The palladium heterogeneous catalyst demonstrated excellent catalytic activity and very high recycling ability in the above two carbonylation reactions. The palladium heterogeneous catalysts showed an excellent stability under carbon monoxide and under the experimental conditions.
