As the third category of chiral catalysts after enzymes and metals, organocatalysts offer advantages such as easy synthesis, low cost, mild reaction conditions, and no metal residue, making them an important pathway to achieving “perfect reaction chemistry.”

      Chiral thioureas, a novel class of hydrogen-bond donor organocatalysts, can activate substrates and control stereoselectivity via hydrogen bonding interactions. They exhibit excellent catalytic activity and enantioselectivity in a range of asymmetric reactions, including the Strecker reaction, Michael reaction, Mannich reaction, Aza-Henry reaction, Aldol reaction, Baylis-Hillman reaction, and Friedel–Crafts reaction.

      Strem Chemicals, with over 50 years of experience in producing high-purity catalysts, ligands, organometallics, and other specialty chemicals, operates under the philosophy that “Poor quality chemicals may kill a great research idea.” The company prioritizes product quality, and its manufacturing facilities are FDA cGMP-certified.
