Dichotomy of Atom-Economical Hydrogen-Free Reductive Amidation vs Exhaustive Reductive Amination
Kolesnikov, Pavel N.,Usanov, Dmitry L.,Muratov, Karim M.,Chusov, Denis
supporting information, p. 5657 - 5660 (2017/10/25)
Rh-catalyzed one-step reductive amidation of aldehydes has been developed. The protocol does not require an external hydrogen source and employs carbon monoxide as a deoxygenative agent. The direction of the reaction can be altered simply by changing the solvent: reaction in THF leads to amides, whereas methanol favors formation of tertiary amines.
Acetic acid as a catalyst for the N-acylation of amines using esters as the acyl source

We report a cheap and simple method for the acetylation of a variety of amines using catalytic acetic acid and either ethyl acetate or butyl acetate as the acyl source. Catalyst loadings as low as 10 mol% afforded acetamide products in excellent yields at temperatures ranging from 80-120 °C. The methodology can also be successfully applied for the synthesis of a broad range of other amides, including the formation of formamides at 20 °C.
An organocatalytic biomimetic approach to α-aminophosphonates
Kowalczyk, Dorota,Albrecht, Lukasz
supporting information, p. 3981 - 3984 (2015/03/30)
A novel biomimetic approach to optically active α-aminophosphonates utilizing readily available acylphosphonates and 2-chlorobenzylamine as starting materials has been described. The enantioselective protonation constitutes the main enantiodifferentiating step in the developed strategy. This nature-inspired approach proceeds efficiently and in a highly stereoselective manner.

H-β-zeolite catalyzed transamidation of carboxamides, phthalimide, formamides and thioamides with amines under neat conditions
Rao, Sadu Nageswara,Chandra Mohan, Darapaneni,Adimurthy, Subbarayappa
, p. 95313 - 95317 (2015/11/24)
Efficient transamidation of unactivated carboxamides, phthalimides, formamides and thioamides with amines under solvent-free conditions using H-β-zeolite as a green and recyclable heterogeneous catalyst is described. Easy work up, high purity of the products, recyclability and environmentally-friendly nature of the catalyst are the attractive features of the present methodology. This is the first report for the transamidation of thioamides under heterogeneous conditions.

Well-defined robust ruthenium(II) complexes 3a-d bearing o-aryloxide-N-heterocyclic carbene ligands with different wingtip substituents (3a (R = Me), 3b (R = Ph), 3c (R = iPr) and 3d (R = Mes)) in the imidazole ring were synthesized in good yields by the reaction of imidazolium proligands with metal precursor [RuHCl(CO)(PPh3)3] by transmetallation from the corresponding silver carbene complexes. All the Ru(II)-NHC complexes have been characterized by elemental analyses, spectroscopic methods as well as ESI mass spectrometry. The molecular structure of the complex 3a was identified by means of single-crystal X-ray diffraction analysis, which revealed that the complexes possess a distorted octahedral geometry. In order to explore the catalytic potential of the synthesized complexes, all the four [Ru-NHC] complexes [3a-d] were tested as catalysts for transamidation of carboxamides with amines. Notably, the complex 3a was found to be very efficient and versatile catalyst toward transamidation of a wide range of amides with amines.

In the presence of a catalytic amount of l-proline (10 mol %), transamidations of carboxamides with amines were achieved under solvent-free conditions. The transamidation process is compatible with a wide range of amines.
A novel and simple transamidation of carboxamides in 1,4-dioxane without a catalyst
Vanjari, Rajeshwer,Allam, Bharat Kumar,Singh, Krishna Nand

An easy acylation and formylation of amines has been achieved via transamidation using 1,4-dioxane. The investigation works efficiently without an added catalyst and completes within short time under microwave irradiation.
Benzyl amide-ketoacid inhibitors of HIV-integrase
Walker, Michael A.,Johnson, Timothy,Naidu, B. Narasimhulu,Banville, Jacques,Remillard, Roger,Plamondon, Serge,Martel, Alain,Li, Chen,Torri, Albert,Samanta, Himadri,Lin, Zeyu,Dicker, Ira,Krystal, Mark,Meanwell, Nicholas A.

Integrase is one of three enzymes expressed by HIV and represents a validated target for therapy. Previous reports have demonstrated that the diketoacid-based chemotype is a useful starting point for the design of inhibitors of this enzyme. In this study, one of the ketone groups is replaced by a benzylamide resulting in a new potent chemotype. A preliminary SAR study is carried out to investigate the substitution requirements on the phenyl ring and methylene group of the benzylamide.
Synthesis of functionalized pyrroles by reaction of 3,4-diacetylhexane-2,5- dione with primary amines in water

3,4-Diacetylhexane-2,5-dione (tetra-acetylethane) undergoes a complex reaction with primary amines in boiling water to produce N-alkyl-3-acetyl-2,5- dimethylpyrroles, together with small quantities of N-alkyl-3,4-diacetyl-2,5- dimethylpyrroles and 2,5-dim
