Professor Heller and coworkers are engaged in the development of mild and chemoselective acylation reactions using carbonylazole-derived reagents. To that end, they have developed a suite of carbonylimidazole derivatives for facile and chemoselective esterification (MImC, etc.) and amidation (WImC) of carboxylic acids, in collaboration with Professor Richmond Sarpong.

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