Research in the Evano Group


The major part of our research is focused on the development of new processes in organic synthesis using copper-catalysis and copper-mediated transformations. More specifically, we have been involved in the use of copper-catalysis in natural and/or bioactive products, for the development of new processes in organic synthesis and ynamide chemistry and, more recently, in the development of new copper-catalyzed polymerization processes, all these research programs being strongly interconnected. Selected examples of these research activities are briefly described below.



Natural/bioactive products synthesis

Natural products and total synthesis have long been a source of inspiration and motivation as well as considerable innovation and are one of the core of our research. They represent a unique opportunity for the fine-tuning of original techniques which have allowed us to gain access to the target molecules shown below or to their advanced precursors. Among other processes developed en route to these natural products, we have designed original copper-catalyzed cyclization and macrocyclization reactions that enabled straightforward and original preparations of various alkaloids and other natural products .

New processes in Copper Catalysis / copper organometallic chemistry

We are equally involved in another research direction: copper catalysis and development of new copper-mediated transformations for organic synthesis. In this area, we have developed for example a new pathway to pyrrolindoles, a structural motif which is found in numerous natural or biologically active products, and designed various efficient processes for the synthesis of heterosubstituted alkenes and alkynes. More recently, we also have started to study the reactivity of stable organocopper reagents such as copper acetylides under oxidative conditions, which led to the development of efficient alkynylation procedures under especially mild and neutral conditions. These reactions we have developed are now commonly used in the group for the development of the chemistry of ynamides and for natural product synthesis as well.

Chemistry of Ynamides

We have started in 2009 a research program aimed at the development of the chemistry of ynamides, most useful building blocks in organic synthesis whose chemistry is under intense exploration. In order to bring significant developments in this area, we have studied the chemistry of ynamides using a global approach involving the development of new and general ynamide syntheses, the design of new transformations with these building blocks and a combined theoretical/experimental approach to better apprehend their reactivity. In this context, we have reported three generations of ynamides syntheses based on copper-mediated transformations with dibromoalkenes, potassium alkynyltrifluoroborates and copper acetylides. These complementary routes allow the preparation of most classes of ynamides and are routinely used on a multigram scale in the lab (and teaching lab as well). We have also developed new processes with ynamides such as, for examples, new syntheses of dihydropyridines, pyridines, aminovinylphosphonates, fluoroenamides or complex polycyclic molecular scaffolds.
