Biomimetic synthesis of natural products via reactions of ortho-quinone methides
… products. This thesis will describe the use ortho-quinone methides and cascade reactions towards the biomimetic synthesis of the penilactones A and B, the peniphenones A-D, virgatolide B and epicolactone. The total synthesis of ent-penilactone A and penilactone B has been achieved via …

Detection of Polypeptide Interactions Via Periodate Triggered Dopa Crosslinking
… biologist. We have developed a novel, bioorthogonal cross-linking chemistry based upon periodate mediated oxidation of the artificial amino acid 3,4- Dihydroxyphenylalanine to a resultant ortho-quinone. This ortho-quinone was proven capable of capturing either cysteine, lysine, histidine, …

Synthesis of sesquiterpene-tropolones
… hetero-Diels–Alder reaction between a tropolone ortho-quinone methide and derivatives of α–humulene. Concise and scalable syntheses of both fragments are described, as well as alternative approaches to key intermediates. During the development of the tropolone synthesis, an unprecedented …

Total synthesis of oxaphenalenone natural products
… synthetic operations to assemble a masked ortho-quinone methide (o-QM) bearing the OP framework via interrupted Rieche formylation. The masked o-QM intermediate was utilized in the syntheses of additional OP natural products such as SF226 and the para-quinone methide (p-QM) corymbiferone C, …

Method Development Towards Catalytic Transformations of Reactive Intermediates
… highly reactive intermediates, including ortho-quinone methides (o-QMs) and benzylic carbocations, from simple and easily accessed starting materials. The primary goals of each project were to access bioactive material or value added chemicals via the simplest and shortest route possible, …

A Lewis Acidic Stroll Through the p-Block
… Phosphorus(V) dications containing both an ortho-quinone and terpyridine backbone were prepared and shown to effect the Lewis acid-mediated hydrodefluorination (HDF) of fluoroalkanes with silanes, despite the phosphorus center being coordinately saturated. Computational data support the …
