Collection: Chiral Auxiliaries

Chiral Auxiliaries — contains chiral molecules temporarily attached to a substrate to direct the stereochemistry of a reaction, including oxazolidinone derivatives, camphor sultams, and prolinamides in both R and S configurations. These auxiliaries are removed after the transformation is complete, so the final product is obtained as a single enantiomer.

Synthetic chemists use chiral auxiliaries in asymmetric synthesis for aldol reactions, enolate alkylation, Diels-Alder reactions, and diastereoselective acylation to control the formation of new stereogenic centers. Evans oxazolidinone and camphorsultam derivatives are commonly used in the synthesis of natural products and in the development of complex chiral molecules that require high stereochemical control.

Pay attention to the absolute configuration (R or S), enantiomeric purity (ee), and the linking functional groups (carboxamide, sulfonamide) that determine compatibility with the target reaction. All products are original Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
