« Superelectrophilic activation in superacid: A new route to labelled metabolites»
Reactions under superacid conditions1 which allow to develop unprecedented organic processes for direct and
original modification of organic compounds, from fine chemicals to polyfunctionalized bioactive molecules, are
now widespread reactions in synthetic chemistry. 2 The exploitation of the superacid properties (ability to
generate long-lived intermediates, (poly)protonation of substrates and generation of superlectrophiles, 3 CH
functionalization, …) led us to develop original synthetic methodologies to deliver in a straightforward way
(fluorinated) nitrogen containing compounds coming from high valued synthetic building blocks to bioactive
compounds. 4 Since 2005, the group is also engaged in a fruitful collaboration with the society @rtMolecule.
@rtMolecule specializes in the custom synthesis of milligram to gram quantities of stable isotope labelled
materials (D, 13C, 15N, 18O), metabolites and reference standards (API, impurities, by products,...).
Biomimetic reactions have recently become methodologies of choice in the search for new chemical processes.
For example, the search for innovative methods to mimic the enzymatic reactions is deeply growing. 5 Many
transformations taking place within the enzyme sites can be described as acid-catalyzed reactions. Because of
the unique geometry of enzyme active sites and high ionic concentration within them, these reactions are highly
dependent on multiple interactions (chelation / protonation). As mentioned by Pr. Olah in his autobiography6 or
reported by Thauer and Murphy, 7 these phenomena can be reasonably related to the interactions that take place
during the superelectrophilic activation (polyprotonation) of substrates in superacid medium. One of the
objectives of the thesis is by using superacid chemistry to develop new methods that mimic the metabolic
transformations (and especially hydroxylation). These new biomimetic transformations applied to elaborated
bioactive compounds should allow to deliver in a straightforward way, metabolites and key rare analytical
standards, making this method a new tool for pharmaceutical industry. Synthetic and efficient routes to the
targeted labeled metabolites will also be explored.
