Tandem Transformation of Aldoximes to N-Methylated Amides Using Methanol

Tandem conversion of aldoximes to N-methylated amides with methanol in presence of a single Ru(II) catalyst is accomplished through the Ru(II)-mediated rearrangement followed by the reductive N-methylation. Employing this protocol, several aldoximes were directly transformed to the N-methylated amides using methanol. Kinetic experiments with H218O advocated that the aldoxime is acted as the nucleophile during the aldoxime to amide rearrangement process. Involvement of nitrile intermediate during this transformation is realized from the kinetic study. (Figure presented.).

Atom-Economical and Tandem Conversion of Nitriles to N-Methylated Amides Using Methanol and Water

A cobalt complex catalyzed tandem conversion of nitrile to N-methylated amide is described using a methanol and water mixture. Using this protocol, several nitriles were directly and efficiently converted to the desired N-methylated amides. Kinetic experiments using H2O18 and CD3OD suggested that water and methanol were the source of the oxygen atom and methyl group, respectively, in the final N-methylated amides. Importantly, the participation of active Co(I)-H species in this transformation was realized from the control experiment. The kinetic isotope effect (KIE) study suggested that the activation of the C-H bond of methanol was a kinetically important step. The Hammett plot confirmed that the reaction was faster with the electron deficient nitriles. In addition, the plausible pathway for the formation of N-methylated amides from the nitriles was supported by the computational study.

Chemoselective Synthesis of Aryl Ketones from Amides and Grignard Reagents via C(O)-N Bond Cleavage under Catalyst-Free Conditions

Conversion of a wide range of N-Boc amides to aryl ketones was achieved with Grignard reagents via chemoselective C(O)-N bond cleavage. The reactions proceeded under catalyst-free conditions with different aryl, alkyl, and alkynyl Grignard reagents. α-Ketoamide was successfully converted to aryl diketones, while α,β-unsaturated amide underwent 1,4-addition followed by C(O)-N bond cleavage to provide diaryl propiophenones. N-Boc amides displayed higher reactivity than Weinreb amides with Grignard reagents. A broad substrate scope, excellent yields, and quick conversion are important features of this methodology.

Ruthenium-Catalyzed Synthesis of N-Methylated Amides using Methanol

An efficient synthesis of N-methylated amides using methanol in the presence of a ruthenium(II) catalyst is realized. Notably, applying this process, tandem C-methylation and N-methylation were achieved to synthesize α-methyl N-methylated amides. In addition, several kinetic studies and control experiments with the plausible intermediates were performed to understand this novel protocol. Furthermore, detailed computational studies were carried out to understand the mechanism of this transformation.

I2-Catalyzed Oxidative Amidation of Benzylamines and Benzyl Cyanides under Mild Conditions

We report a novel and efficient method for the oxidation of benzylic carbons (amines and cyanides) into corresponding benzamides using a catalytic amount of I2 and TBHP as the green oxidant via the C-H bond cleavage of the benzylic carbon under mild reaction conditions. According to the literature survey, this is the first report for the oxidative amidation of benzylamines and decyanation of benzyl cyanides in one pot under metal-free conditions.

Ruthenium-catalyzed oxidative decyanative cross-coupling of acetonitriles with amines in air: A general access to primary to tertiary amides under mild conditions

Catalyzed by Ru and in the presence of air and nucleophiles such as amines or ammonia, activation of the C-CN bond could be easily achieved under mild conditions to produce primary to tertiary amides in good to excellent yields. The use of accessible and functional-group-tolerant starting materials, a cheap, low-loading and recyclable catalyst, ligand-free conditions and excellent product yields are the advantages of the method. Moreover, compared with the Ritter reaction and hydration methods, this novel reaction has more comprehensive application scope.

One-Pot Direct Synthesis of Weinreb Amides from Aryl and Hetero Aryl Halides Using Co 2(CO) 8 as an Effective CO Source under Conventional Thermal Heating

A successful protocol for the synthesis of Weinreb amides directly from aryl halides via aminocarbonylation with N,O-dimethyl hydroxylamine using Co2(CO)8 as an in situ CO source has been demonstrated. The effects of various reaction parameters such as temperature, base, and CO source have also been investigated and optimized. GRAPHICAL ABSTRACT.

Copper-catalyzed N-methylation of amides and O-methylation of carboxylic acids by using peroxides as the methylating reagents

The copper-catalyzed N-methylation of amides and O-methylation of carboxylic acids by using peroxides as the methylating reagent are described. Various amides and carboxylic acids were methylated affording N-substituted amides and esters. Tentative mechanistic studies suggest that this reaction is likely to involve a radical process.
