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.
Copper(ii)-catalyzed c-n coupling of aryl halides and n-nucleophiles promoted by quebrachitol or diethylene glycol

supporting information, p. 2161 - 2168 (2019/11/25)
Herein, we report the natural ligand quebrachitol (QCT) as a promoter for a Cu(II) catalyst, which is highly effective for N-Arylation of various amines and related aryl halides. A series of diarylamine derivatives were obtained in high yields by using diethylene glycol (DEG) as both ligand and solvent. The C-N coupling reactions proceed under mild conditions and exhibit good functional group tolerance.
Palladium-catalyzed coupling reaction of amino acids (esters) with aryl bromides and chlorides
Ma, Fangfang,Xie, Xiaomin,Ding, Lina,Gao, Jinsheng,Zhang, Zhaoguo
experimental part, p. 9405 - 9410 (2011/12/14)
The bulky and electron-rich MOP type ligands and Pd(dba)2 combinations showed high efficiency for the coupling reactions of amino acids and inactive aryl halides to give N-aryl amino acids. Under the catalytic conditions, not only α-amino acids, but also β-, γ-, and δ-amino acids have been coupled with aryl chlorides in moderate to high yields; in the case of optically pure β-amino acids as substrates, the optical purities of the coupling products retained.
