We present a four-step synthesis of (+)-artemone from (–)- linalool, featuring iminium organocatalysis of a doubly diastereoselective conjugate addition reaction. The strategy follows a proposed biosynthetic pathway, rapidly generates stereochemical complexity, uses no protecting groups, and minimizes redox manipulations.
Synthesis, Characterization, And Catalytic Applications Of Porous Transition-Metal Oxide Systems For The Conversion Of Biomass, Anton Gudz
Honors Scholar Theses
The development of innovative strategies and environmentally-friendly resources for the sustainable production of fuels and chemicals from renewable materials has recently received much interest in the scientific world. Among such resources, biomass has enormous potential as a raw material for generation of green fine chemicals to replace the petroleum feedstocks currently in place. Biomass derived carbohydrates can be converted into such valuable platform chemicals as levulinates, 5-hydroxymethyl furfural (HMF), and lactates. In order to catalyze the biomass conversion process, porous transition-metal oxide catalytic systems have been developed in this study. High catalytic activities and potential for reusability of such systems …
Synthesis Of Pyridone Ligands And Iron Precursors For The Development Of Iron-Based Hydrogenation Catalysts, Becky Hanscam
Synthesis Of Pyridone Ligands And Iron Precursors For The Development Of Iron-Based Hydrogenation Catalysts, Becky Hanscam
Summer Research
Green chemistry is concerned with the development of safer, more efficient, and more environmentally acceptable chemical products and processes. An important aspect of green chemistry is the reduction of chemical waste. Catalysis is essential to achieving such a transformation. Hydrogenation is an example of an industrially important catalytic process. Hydrogenation reactions are common in the pharmaceutical industry as they provide a cost-effective and reliable approach to a wide range of compounds. However common hydrogenation catalysts are composed of expensive and toxic metals. The goal this research is to develop hydrogenation catalysts, based on iron, that will be less expensive and …

The environment is affected by the actions of mankind in multitudinous ways, many of which are detrimental, giving rise to pollution and toxic waste, ultimately making our planet less inhabitable. While remediation and new regulations help to prevent pollution and toxic waste, there is also a need to change the behavior of future generations of consumers and producers of new products. Future chemists and innovators are charged with the responsibility of developing new chemical processes and products that not only meet the needs of our growing population (in terms of energy, clean water and food), but also protect human health …
Developing Catalysts For Improving Direct Amide Formation, Courtney Carley
Developing Catalysts For Improving Direct Amide Formation, Courtney Carley
Summer Research
The widespread occurrence of the amide functional group in the pharmaceutical industry and its prevalence in biological structures such as proteins illustrate the huge impact that amides have on our daily lives. Current methods of forming amides are expensive and harmful to the environment, so there is a need for the development of greener processes for the formation of amides. The first objective of this research is to synthesize catalysts for the direct formation of amides from carboxylic acids and amines. Previously developed catalysts for this transformation are not active enough, and are thus rarely used. The new catalysts to …
The Green Chemistry And Filipino Approach To High School Experiments In Saint Paul College Pasig, Ronald G. Santos, Armando M. Guidote Jr
The Green Chemistry And Filipino Approach To High School Experiments In Saint Paul College Pasig, Ronald G. Santos, Armando M. Guidote Jr
Chemistry Faculty Publications
This paper is a call for teachers to initiate measures in improving the quality of high school chemistry education in the Philippines and that is by going back to practical laboratory work. The experiment presented in this paper is a proof to the possibility of tailor-made experiments that integrate principles of green chemistry. Integrating green chemistry concepts in the design of high school chemistry experiments makes students aware of the responsibility that goes with the use and production of chemicals. Moreover, the experiment was designed to consciously integrate aspects of Filipino culture, values, and traditions. Such enculturation of chemistry by …
