Stress relief: Exercising Lewis acid catalysis for donor-acceptor cyclopropane ring-opening annulations, a basis for new reaction methodologies
… to assemble diverse polycycles, donor-acceptor cyclopropanes are useful, versatile synthetic equivalents for C-C bond formations. By taking advantage of the strain within these unique, polarized systems, differing molecular architectures can be accessed directly to perform contemporary organic …

The Chemistry of Cyclopropylarene Radical Cations
Cyclopropane derivatives are frequently utilized as "probes" for radical cation intermediates in a number of important chemical and biochemical oxidation. The implicit assumption in such studies is that if a radical cation is produced, it will undergo ring opening. Through a detailed examination of …

Application of Mn(III) Oxidative Cyclizations to Natural Product Synthesis
… containing heterocycles. Exploration of a cyclopropane ring opening reaction using indoline, and subsequent manganese(III) cyclization chemistry will be presented as a possible route towards a family of natural products called the flinderoles. Work on the construction of the core of several …

Development of New N-Cyclopropyl Based Electron Transfer Probes for Cytochrome P-450 and Monoamine Oxidase Catalyzed Reactions
… is presented in Chapter 2. The barrier for ring opening of aminyl radical cations derived from N-cyclopropyl derivatives of tertiary amines (such as MPTP) is expected to be low. Reactions of 3BP with all three compounds are very similar. The results suggest that the reaction between …
