Description

(-)-Taddol CAS NO 93379-48-7 is a highly versatile and enantiomerically pure chiral ligand and catalyst. Its value lies in its ability to induce high stereoselectivity in a wide range of asymmetric organic transformations, which is critical for producing single-enantiomer compounds. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require precise control over molecular chirality for the development of active ingredients and advanced materials.

Application

• As a chiral ligand in asymmetric catalysis, including additions to carbonyl groups.
• For enantioselective synthesis of pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• In the preparation of chiral auxiliaries and building blocks for complex organic molecules.
• As a key component in asymmetric alkylation and allylation reactions.
• For research and development in methodology development for new stereoselective transformations.
• In the synthesis of agrochemicals and flavors & fragrances where specific stereochemistry is required.
