Product Name:(S)-α,α-Bis(4-methylphenyl)-2-pyrrolidinemethanol
English Name:(S)-α,α-Bis(4-methylphenyl)-2-pyrrolidinemethanol
CAS No.:131180-52-4
Aliases:(S)-α,α-Bis(4-methylphenyl)prolinol, (S)-2-[Bis(4-methylphenyl)hydroxymethyl]pyrrolidine, (S)-α,α-Bis(4-methylphenyl)pyrrolidine-2-methanol
Molecular Formula:C19H23NO
Physical Properties:White to off-white crystalline powder; soluble in methanol, ethanol, chloroform and other organic solvents; sparingly soluble in water. Melting point approximately 80–90°C. It is chiral and exhibits good stability to air and light; however, it is recommended to be stored sealed in a cool, dry place away from moisture.
Uses:This product is a chiral pyrrolidinol-type ligand widely used in asymmetric synthesis as an organocatalyst or metal-complex ligand. It serves effectively in enantioselective reactions such as asymmetric alkylation of aldehydes, 1,2-nucleophilic addition to ketones, and Michael addition, providing excellent enantioselectivity and serving as a key building block for chiral pharmaceutical intermediates.
Technical Specifications:
Appearance: white to off-white crystalline powder
Purity: ≥98% (HPLC)
Specific rotation: [α]D20 approx. -75° (c=1.0, CHCl3)
Molecular weight: 281.39
Storage: keep sealed, protected from light, and stored in a cool dry place
