Collection: Epoxidation [Asymmetric Synthesis]

Epoxidation [Asymmetric Synthesis] — includes chiral reagents such as tartrate derivatives (diethyl, dimethyl, diisopropyl, dibenzyl) and cyclohexanediamine-based salen ligands used in asymmetric catalysis. This group provides a source of chirality to direct stereochemical selectivity in oxidation reactions.

Tartrate esters such as Diethyl D-(-)-Tartrate and Diisopropyl L-(+)-Tartrate act as chiral ligands in Sharpless epoxidation to convert allylic alcohols into epoxides with high enantiomeric selectivity, while salen complexes such as N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamine derivatives are used in Jacobsen epoxidation for unfunctionalized alkenes. Asymmetric synthesis chemists use these tartrate enantiomer pairs to direct products toward the desired stereochemical configuration.

Example products in this collection: TCI T1671 622-00-4 Dibenzyl L-Tartrate, TCI B5613 138124-32-0 (R,R)-(-)-N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminomanganese(III) Chloride, TCI T1659 13171-64-7 Dimethyl D-(-)-Tartrate, TCI D3898 117384-45-9 Di-tert-butyl L-(+)-Tartrate, TCI T1387 62961-64-2 Diisopropyl D-(-)-Tartrate, TCI T0003 87-91-2 Diethyl L-(+)-Tartrate, TCI T1195 13811-71-7 Diethyl D-(-)-Tartrate, TCI T0006 608-68-4 Dimethyl L-(+)-Tartrate.

Selection of products should consider the enantiomer configuration (D or L) and the ester group of the tartrate derivatives, as this choice determines the direction of stereochemical selectivity of the epoxide product formed. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
