Paragraph 0115; 0116, (2017/06/02)
The invention provides a preparation method of a quinoline derivative. The method includes the steps of: in the presence of an oxidizing agent, adding a catalyst, then adding aniline or aromatic amine with different substituents, at the same time adding alcohol for reaction so as to prepare the quinoline derivative by one step. Specifically, the catalyst comprises a metal catalyst, an assistant catalyst I and an assistant catalyst II; the metal catalyst is a transition metal catalyst; the assistant catalyst I is an alkaline nitrogen-containing ligand; and the assistant catalyst II is an acidic compound. The quinoline derivative prepared by the method provided by the invention has stable performance and high purity. And the preparation method of the quinoline derivative can prepare quinoline, 2-methylquinoline, 8-hydroxyquinoline quinoline and other derivatives by one-step reaction, and the preparation method is simple and practicable. The preparation process does not produce new "three wastes", is environment-friendly, and provides a green and environment-friendly synthesis method. The preparation method has the characteristics of few raw material variety, little reaction equipment, few preparation step and low cost, and is more suitable for industrial production.

We report the development of a Pd-catalyzed process for the stereospecific cross-coupling of unactivated secondary alkylboron nucleophiles and aryl chlorides. This process tolerates the use of secondary alkylboronic acids and secondary alkyltrifluoroborates and occurs without significant isomerization of the alkyl nucelophile. Optically active secondary alkyltrifluoroborate reagents undergo cross-coupling reactions with stereospecific inversion of configuration using this method.
