Precision bioconjugation techniques are essential for constructing well-defined protein-based therapeutics such as antibody-drug conjugates (ADCs). Among native amino acids, cysteine is particularly attractive for site-selective modification due to its high nucleophilicity and low natural abundance. However, most proteins contain multiple free cysteines, making it challenging to target specific residues without affecting protein structure or…
The photochemical oxidative coupling of phenols with a range of coupling partners will be described. Even though the reaction likely involves radical intermediates, selectivity can be controlled by selecting coupling partners with different oxidation and nucleophilicity profiles. In addition, the use of donor acceptor complexes permit coupling with partners that have lower oxidation potentials than the phenols. The use of solid photocatalysts…
Reasoning about structure, reactivity, and chemical processes is a critical competency for organic chemistry students. Yet many students cannot fully interpret or explain the underlying chemical reasoning behind the many representations we use to depict chemical phenomena. We need to know more about how to scaffold students reasoning as they learn to translate and make meaning of the symbols and language of organic chemistry. In this talk, I…
