Benzoin, (-)-丨CAS 5928-66-5

(-)-Benzoin is a chiral hydroxy ketone widely used in organic synthesis, pharmaceuticals, and asymmetric catalysis. It serves as a key intermediate for the preparation of α-hydroxy ketones, chiral ligands, and optically active compounds. In medicinal chemistry, (-)-benzoin is used for the synthesis of biologically active molecules, including antiviral, antibacterial, and anticancer agents. It is also applied in asymmetric reactions, such as the benzoin condensation, where it acts as a nucleophilic catalyst or a chiral building block for producing enantioenriched products. Additionally, (-)-benzoin finds use in fragrance and flavor industries due to its aromatic character, contributing to certain synthetic perfumes and flavors.

The benefits of (-)-benzoin lie in its chirality, reactivity, and versatility. Its optically active hydroxy ketone functionality allows enantioselective transformations, enabling the production of chiral intermediates and fine chemicals with high stereochemical control. The hydroxyl and carbonyl groups provide reactive sites for diverse chemical modifications, supporting multi-step synthetic strategies. Its stability under standard laboratory conditions and compatibility with common solvents enhance handling and usability. Overall, (-)-benzoin provides a reliable platform for both research and industrial-scale asymmetric synthesis, improving selectivity and efficiency.
