Description

(2S,4S)-(-)-2-(Diphenylphosphinomethyl)-4-(Dicyclohexylphosphino)-n-Methyl-1-Pyrrolidinecarboxamide, Min. 97% (S,S-Mccpm) is a high-purity, chiral phosphine ligand essential for advanced asymmetric catalysis. This compound matters because it enables highly selective and efficient synthesis of complex chiral molecules, which are critical for developing active pharmaceutical ingredients (APIs) and fine chemicals. It is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors who require precise stereochemical control in their synthetic processes.

Application

• Asymmetric Hydrogenation: A key ligand for the enantioselective reduction of prochiral olefins, ketones, and imines in API synthesis.
• Pharmaceutical Intermediate Synthesis: Enables the production of chiral building blocks for drugs targeting central nervous system, cardiovascular, and metabolic diseases.
• Agrochemical Manufacturing: Used in the synthesis of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Cross-Coupling Catalysis: Facilitates asymmetric versions of Suzuki, Heck, and other cross-coupling reactions for C-C bond formation.
• Academic & Process Chemistry Research: A valuable tool for developing new catalytic methodologies and optimizing reaction pathways in R&D laboratories.
• Fine Chemical Production: Applied in the manufacture of chiral flavors, fragrances, and advanced materials.
