Objective:
The long-term objective of this research project is to develop various environmentally friendly chemical syntheses using water, liquid CO2, and ionic liquid as nonpolluting solvents. The specific objective during this funding period is to study new carbon-carbon bond formation reactions that do not use anhydrous organic solvent, avoids the use of protection-deprotections, is applicable to large-scale industry operation, and has a reduced impact on environment due to the use of catalytic amount of metal and/or in-process recycling.
Progress Summary:
Metal-mediated carbon-carbon bond formation is one of the most important fundamental reactions in organic chemistry and is widely used in various chemical and pharmaceutical processes. Traditionally, they are conducted in anhydrous organic solvents, are air-sensitive, and are potentially explosive. The present study investigates the scope, mechanism, and synthetic application of metal-mediated reactions through the use of water solvent. During this period, we have investigated and succeeded metal-mediated carbon-carbon bond formations involving SP3 hybridized C-X bonds, SP2 hybridized C-X bonds, and SP hybridized C-X bonds. The method saves synthetic steps by avoiding many protection and deprotection processes and contributes to overall synthetic efficiency and a reduction in organic emission. Additional research is planned to transform the reaction into a catalytic process. Additionally, the uses of liquid CO2 and ionic liquid as nonpolluting solvent for carbon-carbon bond formations also have been investigated during this period. A Barbier-type reaction in liquid CO2 and a novel synthesis of tetrahydropyran derivatives have been synthesized in ionic liquids for the first time. These methods provided cleaner approaches for synthesizing complex pharmaceuticals (currently, the industry that generates the largest amount of waste/per Kg of products).
During the second budget year, we have further evaluated metal-mediated carbon-carbon bond formations and related reactions in the synthesis of C-glycoside-type natural products. Research activities have been focused on the syntheses of natural products (+)-bergenin. Substantial progresses have been made on the syntheses of all these biologically important compounds. We have developed a novel one-step process that can be used to generate tetrahydropyranols that will have important applications in the synthesis of C-glycoside natural products. We also have developed a palladium-catalyzed formation of carbon-carbon bonds in air and water. Such results have both theoretical and practical values.
During this year, 10 graduate students, 4 postdoctoral students, and 2 undergraduate students have benefited either directly or indirectly from the support of this project. These students have gained valuable experience in organic synthesis and structural characterizations.
During the first budget year, the principal investigator (PI) has further polished the short precourse, entitled "The World of Organic Chemistry." The course was scheduled before the regular organic chemistry text. At the end of the course, each student wrote an essay with the title: "Chemistry and Me." All the students were very enthusiastic about this part of the course with well-written essays. The PI also has added new experiments and variation to the public outreach program. The PI conducted two science demonstrations in a public elementary school. All the students were extremely interested in the demonstration and in chemistry. A graduate student also was involved in the outreach.
Future Activities:
We will continue our work towards the project objectives. A major objective is to further greening such reactions in water, liquid CO2, and ionic liquids.
