Myo-inositol is originally applied as a cardiovascular medicine in clinic, which can be multi-ton manufactured via extraction from the byproducts in agricultural product processing such as defatted rice bran and corn-soaking water. Herein, the application of myo-inositol (MI) as a novel versatile tridentate O-donor ligand has been first described for promoting Cu-catalyzed amination reaction in aqueous medium.

Room temperature N-arylation of amino acids and peptides using copper(i) and β-diketone

supporting information, p. 4637 - 4641 (2015/04/27)
A mild and efficient method for the N-arylation of zwitterionic amino acids, amino acid esters and peptides is described. The procedure provides the first room temperature synthesis of N-arylated amino acids and peptides using CuI as a catalyst, diketone as a ligand, and aryl iodides as coupling partners. The method is equally applicable for using relatively inexpensive aryl bromides as coupling partners at 80 °C. Using this procedure, electronically and sterically diverse aryl halides, containing reactive functional groups were efficiently coupled in good to excellent yields.
Efficient copper-catalyzed N-arylations of nitrogen-containing heterocycles and aliphatic amines in water
Li, Xufeng,Yang, Daoshan,Jiang, Yuyang,Fu, Hua
experimental part, p. 1097 - 1105 (2010/08/06)
A simple and efficient copper-catalyzed method has been developed for N-arylations of nitrogen-containing heterocycles and aliphatic amines in water. The protocol uses (1E,2E)-oxalaldehyde dioxime (OADO) as the ligand, and water as the solvent, and shows good tolerance towards various functional groups.

2-Pyridinyl β-ketones were identified as new efficient ligands for CuI-catalysed N-arylation of aliphatic amines at room temperature with great selectivity and substrate scope tolerance.
A mild and efficient method for copper-catalyzed Ullmann-type N-arylation of aliphatic amines and amino acids
Jiang, Qun,Jiang, Deshou,Jiang, Yuyang,Fu, Hua,Zhao, Yufen
, p. 1836 - 1842 (2008/02/10)
An efficient and general protocol for copper-catalyzed N-arylation of aliphatic amines and amino acids has been developed using aryl iodides under mild conditions (coupling temperature at 25-35°C). For the N-(o-nitrophenyl) amino acid derivatives, subsequent reduction of the nitro group in the presence of tin(II) chloride resulted in 3,4-dihydroquinoxalin-2(1H)-one derivatives in good yields.

Kinetics and mechanism of thermal gas-phase elimination of α- and β- (N-arylamino)propanoic acid: Experimental and theoretical analysis
Al-Awadi, Sundus A.,Abdallah, Mariam R.,Hasan, Mohamad A.,Al-Awadi, Nouria A.
, p. 3045 - 3049 (2007/10/03)
2-(N-Phenylamino)propanoic acid 1a and 3-(N-phenylamino)-propanoic acid 2a together with four of their aryl analogues were pyrolysed in the gas-phase. The reactions were homogeneous and free from catalytic and radical pathways. Analysis of the pyrolysate of 1 showed the elimination products to be carbon monoxide, acetaldehyde and aniline, while the pyrolysate of 2 reveals the formation of acrylic acid in addition to aniline. Theoretical study of the pyrolysis of 2 using an ab initio SCF method lend support to a reaction pathway involving a 4-membered cyclic transition state.
Enantioselective hydrolysis of some 2-aryloxyalkanoic acid methyl esters and isosteric analogues using a penicillin G acylase-based HPLC monolithic silica column

A technique based on liquid chromatography has been developed to facilitate studies of enantioselectivity in penicillin G acylase (PGA)-catalyzed hydrolysis of some 2-aryloxyalkanoic acid methyl esters and isosteric analogues. PGA was covalently immobilized on an aminopropyl monolithic silica support to create an immobilized HPLC-enzyme reactor. Two sets of experimental data were drawn to calculate the enantioselectivity (E) of the kinetically controlled enantiomer-differentiating reaction, the degree of substrate conversion and the enantiomeric excess of the product. The developed enzymatic reactor was coupled through a switching valve to an achiral analytical column for separation and quantitation of the hydrolysis products. The enantiomeric excess was determined off-line on a PGA-chiral stationary phase. In this way, highly precise E values were determined. A computational study related to the hydrolysis of the considered racemic esters was also carried out in order to unambiguously clarify both the substrate specificity and the enantioselectivity displayed by PGA.
