英文摘要: Heterocycles are one of the most important structural motifs in pharmaceutically active compounds and natural products. Searching efficient methods for the synthesis of heterocycles and their derivatives have received great interests from the perspective of medicinal chemistry and organic synthesis. Considering the preference of modern green chemistry for more environmentally friendly materials, the development of an efficient reaction system with recyclable nanometer catalysts is highly desirable. The project will focused on the preparation of nano copper oxide with different structures and developing their catalytic application on the synthesis of heterocycles including C-N, C-O,C-S through C-H functionalization. Nano CuO catalyst with high efficiency and high selectivity will be found through investigating the effects of different nanostructures on catalytic activity. The effects of catalyst, base, solvent, temperature, and reaction time will be studied. The scope and functional group compatibility of the nano CuO catalyzed oxidative C-H functionalization will be investigated in the optimal reaction conditions. Furthermore, the mechanism of this nano catalyzed reaction will be investigated by XRD and SEM analysis of the catalysts after the reaction and ICP analysis of the leaching of the copper from the CuO
