For over a century, the structures and reactivities of strained organic compounds have captivated the chemical community. Whereas triple-bond-containing strained intermediates have been well studied, cyclic allenes have received far less attention. Additionally, studies of cyclic allenes that bear heteroatoms

The Garg group develops methods for the synthesis of natural products and pharmaceuticals. One key method pertains to heterocyclic arynes, such as indolynes and pyridynes, which are generated in situ from silyltriflate precursors under mild fluoride based reaction conditions.

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