Application

Acyltrifluroborates (KAT′s) are bench, air, and moisture stable reagents for rapid, chemoselective amide bond formations with hydroxylamines. These amide bond forming reactions proceed under aqueous conditions, without the need for coupling reagents or protecting groups. This product was introduced in collaboration with the Bode Research Group.

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.
