Natural Product Synthesis, Catalytic Reaction Development, Organometallic Chemistry
Our research focuses on the development of byproduct-free catalytic C-C bond forming reactions of abundant, renewable feedstocks. A central theme involves the identification of new reactivity patterns, the evolution of related catalytic processes and, ultimately, the development of new strategies for the synthesis of natural products or commodity chemicals.
One major area of research involves the development of C-C bond forming hydrogenations and transfer hydrogenations. We have found that diverse π-unsaturated reactants reductively couple to carbonyl compounds and imines under hydrogenation conditions, providing a byproduct-free alternative to stoichiometric organometallic reagents in a range of C=X (X = O, NR) addition processes. This concept is extended further by “C-C bond forming transfer hydrogenations”. Here, alcohol dehydrogenation triggers hydrometallation of π-unsaturated reactants to generate transient organometallics, enabling byproduct-free aldehyde addition directly from the alcohol oxidation level. This body of work represents the first C-C bond forming hydrogenations beyond hydroformylation, and evokes the question of whether all processes employing stoichiometric organometallic reagents can be conducted catalytically under hydrogenation conditions.
