Our group is driven by the passion of discovering new reactivity in organic chemistry, especially using catalysis. Basing on high energy molecules, such as strained rings or cyclic hypervalent iodine reagents for electrophilic alkynylation and other transformations, we develop non-conventional bond disconnections for the synthesis of important building blocks and bioactive molecules, as well as the modification of biomolecules . We also control the regioselective functionalization of alkenes and alkynes using in situ tethering approaches. Regular group meetings and seminars allow us to share and enhance our knowledge and love of organic chemistry.
