A new bis(imino)pyridine compound, 2,6-{(2,6-Me2-C 6H3)NC(t-Bu)}2C5H3N (6), has been synthesized with t-butyl substituents on the imino carbon atoms. The stepwise synthetic method for assem
Organocatalytic Enantioselective Synthesis of Atropisomeric Aryl-p-Quinones: Platform Molecules for Diversity-Oriented Synthesis of Biaryldiols

Presented here is a class of novel axially chiral aryl-p-quinones as platform molecules for the preparation of non-C2 symmetric biaryldiols. Two sets of aryl-p-quinone frameworks were synthesized with remarkable enantiocontrol by means of chiral phosphoric acid catalyzed enantioselective arylation of p-quinones by central-to-axial chirality conversion. These aryl-p-quinones were then used to access a wide spectrum of highly functionalized non-C2 symmetric biaryldiols with excellent retention of the enantiopurity.

A new triketimine (2,6-Me2C6H3N=CMe)2CH(2,6-Me2C6H3N=CBut) (1) was synthesized by the reaction of imidoyl chloride 2,6-Me2C6H3N=CClBu

A novel method for N-(hetero)arylamide synthesis based on rarely explored amine activation, rather than classical acid activation, is reported. The activated amines are easily prepared using a three-component reaction with commercial reagents. The new method shows a broad scope including challenging amides not (efficiently) accessible via classical protocols.
Sulphuric acid immobilized on silica gel (H2SO4-SiO2) as an eco-friendly catalyst for transamidation
Rasheed,Rao, D. Nageswar,Reddy, A. Siva,Shankar, Ravi,Das, Parthasarathi
, p. 10567 - 10574 (2015/02/05)
A novel method of transamidation of carboxamides with amines by using catalytic amounts of H2SO4-SiO2 has been developed under solvent free conditions. The transamidation is compatible with a wide range of aromatic, heteroaromatic, aliphatic, cyclic/acyclic primary or secondary amines. The metal/solvent-free conditions represent a significant improvement over other existing methods as the reaction can be performed in open air conditions and no column purification is required. The versatility of this methodology was further demonstrated by synthesizing the commercially available drug procainamide.

(Chemical Equation Presented) Hydrocarbons activate! Isolable β-diketiminato dicopper-nitrene complexes such as 1 derived from the reaction of [{(Cl2NN)Cu}2(μ-benzene)] and 1-adamantylazide are potent towards nitrene insertion into unactivated sp 3-hybridized C-H bonds. 1 allows stoichiometric and catalytic intermolecular C-H amination of hydrocarbons to give secondary amines (see scheme). Catalyst loadings as low as 0.05 mol% may be used.
Conformational Analysis of Crowded Anilides and Thioanilides. The "En-Face" Steric Effect of Aryl Groups
Pettersson,Ingrid,Sandstroem, Jan
, p. 397 - 406 (2007/10/02)
In order to study the interaction of isobutyl, neopentyl, and isopropyl groups with the "face" of aromatic rings, a series of o,o'-disubstituted anilides and thioanilides with the above-mentioned groups as N-substituents has been investigated by temperatu
DIPHOSPHORUS TETRAIODIDE AS A NEW MILD CONDENSING AGENT FOR THE SYNTHESIS OF AMIDES
Suzuki, Hitomi,Tsuji, Junko,Sato, Naofumi,Osuka, Atsuhiro
, p. 449 - 452 (2007/10/02)
In the presence of diphosphorus tetraiodide, a variety of weak carboxylic acids readily react with amines to form the corresponding amides in high yields.
