Research topics

1- Total synthesis of bioactive products: 
Biologically active compouds are selected as targets either to set up new strategies and new methods, or to highlight the methodologies we develop in other contexts (see below).

TS

2- New methodologies :
We are developing new methods within the context of Green Chemistry, based on homogeneous and/or heterogeneous catalysis (see below) but also on the use of enzymes and/or carbohydrates.

3. Homogeneous catalysis :
We explore the behavior of selected transition metal catalysis and organometallics, mainly Cu, Ag, Au, in organic synthesis. The mehods we developed are then applied to total synthesis of natural products.

4- Heterogeneous catalysis :
Heterogeneous catalysis is at the heart of many industrial processes, but not much in organic synthesis. We are thus trying to combine both by conceiving and synthesizing new micro-and mesoporous materials, tuned for catalysis, either towards organic synthesis (see § Green Chem.), or towards industrial problems, such as carbonylation, chloration,...

  • Multifonctional catalysis: Polyoxometalates (POM) provide an interesting opportunity to develop new and multifunctional catalysts. We are currently developing Ag, Au-POMs.
    MC
  • Chiral heterogeneous catalysis : Metal organic frameworks (MOF) made of specially designed chiral ligands offer to develop new chiral and heterogeneous catalysts.

5- Green Chemistry :
Towards greener chemistry, we are looking for recyclable, if possible multifunctional, catalysts and applying them in multicomponent and cascade reactions.

  • "Zeo-click synthesis" : Zeolites doped with metals provided a peculiar environment for organic transformations, behaving as nanoreactors and forcing some reactions to proceed, together with new or improved or even reversed (stereo)selectivities. Zeo-click synthesis
  • Zeo-based organic synthesis : We are trying to apply zeo-click chemistry to total synthesis, such as in our Acortatarin synthesis.

6- Chemical tools in biology:
From known RNA 3D structures (X ray, etc), we designed and prepared compounds binding to specific sequences. Biological evaluations showed that this concept is indeed offering new routes towards new antiviral and new antibiotic drugs.
