Synthesis Of Bis(Imino)Pyridine Iron(Ii) Complexes And Development Of Bis(Imino)Pyridine Iron(Ii) Catalyzed Carbene Transfer Reactions, Ban Wang Oct 2019

Synthesis Of Bis(Imino)Pyridine Iron(Ii) Complexes And Development Of Bis(Imino)Pyridine Iron(Ii) Catalyzed Carbene Transfer Reactions, Ban Wang

Masters Theses & Specialist Projects

Metal catalysis of symmetric and asymmetric carbene transfer reactions has been widely applied in natural product synthesis and material science over years. Metal carbene can be easily generated from the extrusion of nitrogen under the catalysis of metal complexes to further undergo various organic reactions, O/N/C-H insertions, cycloadditions, and ylide formations. Currently, the dominant effective catalysts for carbene reactions are built with expensive precious metal, for example, rhodium, ruthenium, palladium, gold. Notably, the effective reactivity and enantioselectivity of the dirhodium(II) catalysts are researched and established over the decades. However, the use of precious metal catalysts is the ...


Photochemical Investigation Of High-Valent Metal-Oxo Intermediates Containing Corrole And Light-Harvesting Porphyrin Ligands, Jonathan Malone Jul 2018

Photochemical Investigation Of High-Valent Metal-Oxo Intermediates Containing Corrole And Light-Harvesting Porphyrin Ligands, Jonathan Malone

Masters Theses & Specialist Projects

In enzymatic and synthetic catalytic oxidations, high-valent iron-oxo intermediates play a vital role as the active oxidant. In this regard, many synthetic metal catalysts are designed as biomimetic models to resemble the active site of Cytochrome P450 enzymes (P450) which are the predominant oxidation catalysts in nature. Vitamin B12 cofactors, with a corrole-like structure corrin, are also utilized in some of the more difficult reactions in nature such as rearrangement and reductase reactions.

In this work, application of the promising photochemical method to corrolecontaining ligands systems showed much success in the generation of manganese(V)-oxo corrole intermediates using two ...


Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella May 2014

Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella

Masters Theses & Specialist Projects

HER2 overexpression in breast cancer tumors predicts lower overall survival. Because of the aggressive nature of HER2 tumors and the association with metastatic disease, the HER2 receptor holds great promise as a therapeutic target in metastatic breast cancer. We are developing small molecule inhibitors that bind to the ATP binding site of the tyrosine kinase domain in order to inhibit tyrosine auto-phosphorylation. This process controls biological pathways that mediate the cell growth. In normal cells this process is highly controlled. We are targeting the modification of the side chain of the hydroxy methyl group of 2-Hydroxy methyl-5,8-dimethoxy-1,4-naphthaquinone. These ...


Oxaliplatin And Oxaliplatin Derivatives: Synthesis, Characterization, And Reactivity With Biologically Relevant Ligands, Amy Poynter May 2012

Oxaliplatin And Oxaliplatin Derivatives: Synthesis, Characterization, And Reactivity With Biologically Relevant Ligands, Amy Poynter

Honors College Capstone Experience/Thesis Projects

Oxaliplatin is a third generation anticancer drug that has proven to be successful in fighting ovarian and testicular cancer. We are interested in determining how oxaliplatin and oxaliplatin derivatives interact with proteins, as well as how that interaction is affected by the size and shape of these platinum compounds. We have synthesized oxaliplatin as it is used in cancer treatment, as well as similar platinum compounds with the same diaminocyclohexane ligand as oxaliplatin but with additional bulk added to the nitrogen atoms. We are reacting oxaliplatin with key amino acids, including methionine, and will be comparing the kinetics of this ...


The Reaction Of Methionine With A Non-C2-Symmetrical Platinum (Ii) Diamine Compound, Nilesh Sahi May 2012

The Reaction Of Methionine With A Non-C2-Symmetrical Platinum (Ii) Diamine Compound, Nilesh Sahi

Honors College Capstone Experience/Thesis Projects

The research that we have conducted has allowed us to discover that the amino acids, methionine (Met) and N-acetyl methionine (N-AcMet), will react in a 1:1 and 1:2 molar ratio with platinum complexes containing bulky diamine ligands. Previous research has allowed us to gain a plethora of information on the experimentation and results of specific bulky diamine ligands such as N,N,N',N'-tetramethylethylenediamine and N,N-diethylethylenediamine. In the current study, we have investigated the bulky diamine ligand of N,N-dimethylethylenediamine, or Me2en. With our focus on the bulk of the Me2en ligand ...
