Welcome to the Didier Group – Our group focuses on the development of new strategies in organic synthesis, with particular interest in four-membered rings and organometallic chemistry. Four-membered ring carbo- and heterocycles have become essential motifs in drug discovery programs. More than offering new chemical space by introducing uncommon building blocks, they allow to escape the ...
