Description

(R)-n-Cyclopentylidene-2-Methylpropane-2-Sulfinamide CAS NO 891782-29-9 is a high-purity chiral sulfinamide building block, specifically the (R)-enantiomer, essential for asymmetric synthesis. This compound serves as a critical chiral auxiliary and ligand in the stereoselective construction of complex molecules, enabling the production of enantiomerically pure intermediates. It is primarily required by pharmaceutical R&D and fine chemical manufacturers for the development of active pharmaceutical ingredients (APIs), agrochemicals, and advanced materials.

Application

• As a chiral auxiliary in the asymmetric synthesis of pharmaceutical intermediates and active ingredients (APIs).
• Utilized as a ligand or catalyst component in enantioselective metal-catalyzed reactions, such as additions to imines.
• Key building block for the research and development of novel agrochemicals and specialty fine chemicals.
• Employed in academic and industrial research for methodological development in organic and medicinal chemistry.
• Used in the synthesis of complex natural products and other stereochemically defined molecules.
