Kinetic and structure–activity studies of the triazolium ion-catalysed benzoin condensation (2020)
Journal Article
Massey, R. S., Murray, J., Collett, C. J., Zhu, J., Smith, A. D., & O'Donoghue, A. C. (2021). Kinetic and structure–activity studies of the triazolium ion-catalysed benzoin condensation. Organic and Biomolecular Chemistry, 19(2), 387-393. https://doi.org/10.1039/d0ob02207a

Steady-state kinetic and structure–activity studies of a series of six triazolium-ion pre-catalysts 2a–2f were investigated for the benzoin condensation. These data provide quantitative insight into the role of triazolium N-aryl substitution under sy...

Unusually high α-proton acidity of prolyl residues in cyclic peptides (2020)
Journal Article
Maguire, O. R., Taylor, B., Higgins, E. M., Rees, M., Cobb, S. L., Simpkins, N. S., Hayes, C. J., & O'Donoghue, A. C. (2020). Unusually high α-proton acidity of prolyl residues in cyclic peptides. Chemical Science, 11(29), 7722-7729. https://doi.org/10.1039/d0sc02508a

The acidity of the α-proton in peptides has an essential role in numerous biochemical reactions and underpins their stereochemical integrity, which is critical to their biological function. We report a detailed kinetic and computational study of the... Read More about Unusually high α-proton acidity of prolyl residues in cyclic peptides.

N-Terminal speciation for native chemical ligation (2020)
Journal Article
Maguire, O. R., Zhu, J., Brittain, W. D., Hudson, A. S., Cobb, S. L., & O’Donoghue, A. C. (2020). N-Terminal speciation for native chemical ligation. Chemical Communications, 56(45), 6114-6117. https://doi.org/10.1039/d0cc01604g

Native chemical ligation (NCL) enables the chemical synthesis of peptides via reactions between N-terminal thiolates and C-terminal thioesters under mild, aqueous conditions at pH 7–8. Here we demonstrate quantitatively how thiol speciation at N-term... Read More about N-Terminal speciation for native chemical ligation.
