Abstract
This research project is concerned with the development and use of eco-friendly reaction media for a variety of organic transformations in the preparation of organic chemicals with potential pharmaceutical applications. These chemicals will then be investigated for their anti-cancer, anti-bacterial and anti-inflammation properties.In this project, different methods were used to synthesize various kinds of ionic liquids. Some new ionic liquids were prepared. In addition, Knoevenagel condensation reactions were investigated in RTILs. For the first time, some neutral ionic liquids such as [BMIM]+[BF4]-, [MeOEtMIM]+[CF3COO]- acted as both catalysts and solvents to promote Knoevenagel reactions. All these experiments indicated that RTILs have a great potential as alternative solvents in synthetic chemistry.
Furthermore, nucleoside chemistry is an important research area in drug discovery. Various chemical modified nucleosides have therapeutic activities. However, these compounds usually have poor solubility in common organic solvents. RTILs such as [MeOEtMIM]+[CH3SO3]- have good dissolving capability for these chemicals. A range of thio-substituted nucleobases and nucleosides with potential pharmaceutical applications have been synthesized in several RTILs. These chemicals will then be investigated for their anti-cancer properties.
