英文摘要: C2-modified chiral pyridines and quinolines are very important organic molecular, which are an important type of structural unit that form many chiral drugs having antiviral and antitumor activities. Therefore, the synthesis of new chiral pyridine and quinoline derivatives have not only great theoretical significance, but also potential applying value in medical research field. On the basis of our study for the direct C(sp3)-H acytivation, this project is the first design and synthesis of chiral binol phosphate and chiral binol phosphorus amide ligands, then 2-alkyl azaarenes as raw materials that addition to C=O or N=N or C=N active double bonds catalyzed by chiral ligands, achieving new methods for the synthesis of new chiral pyridine and quinoline derivatives. In this project, the synthesis of new chiral pyridine and quinoline derivatives bears the virtues such as easy operation, high selectivity, high yield via asymmetric organocatalsis.To the best knowledge of us, the research contents of this project have no reports so far, which have innovative significance and great challenging. The expected research production have great reference value and great learning value for the synthesis of new chiral pyridine and quinoline derivatives.
