N-Heterocyclic Carbene (NHC) Compounds

Rovis has demonstrated that triazolium salt in the presence of a base can act as an N-heterocyclic carbene organocatalyst1 in highly enantioselective intramolecular Stetter reactions.

Knoevenagel Condensation Reaction

Knoevenagel Condensation is an organic reaction named after Emil Knoevenagel. It is a classic C-C bond formation reaction and a modification of the Aldol Condensation.

Bode Group – Professor Product Portal

The Bode Group aims to develop new reactions and reagents for the synthesis of complex molecules. The Bode Group has developed N-mesityl-substituted NHCs as organocatalysts for the catalytic generation of reactive species including activated carboxylates, homoenolates, and enolates. These novel catalysts and reactions have made possible a new generation of highly enantioselective annulations from simple starting materials under mild reaction conditions, usually at room temperature and without added reagents. Furthering the goal of designing new reagents to enable the assembly of complex molecules, the Bode group has developed SnAP reagents for the facile, one-pot conversion of aldehydes into N-unprotected, saturated N-heterocycles, including bicyclic and spirocyclic structures. These easy to handle reagents provide a simple and robust alternative to the challenging and restrictive cross-coupling methods for the functionalization of saturated N-heterocycles.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
