Collection: Privileged Ligands and Complexes [Asymmetric Synthesis]

Privileged Ligands and Complexes [Asymmetric Synthesis] — gathers chiral ligands and related compounds such as substituted BINAP derivatives (XylBINAP, TolBINAP), chiral diamines, cinchona alkaloids, and halogenated binaphthols that are widely used in asymmetric catalysis. This group directs the stereochemical selectivity in forming new chiral centers during catalytic reactions.

Privileged Ligands and Complexes are used in combination with transition metals such as ruthenium or rhodium in asymmetric hydrogenation, catalytic alkylation, and carbon-carbon bond-forming reactions that yield single-enantiomer products. Asymmetric synthesis chemists and process development scientists utilize variations of aryl substituents on the BINAP framework to tune selectivity, while cinchona alkaloids such as cinchonidine function as organocatalysts or resolving agents in chiral resolution.

Example products in this collection: TCI X0071 135139-00-3 (S)-(-)-XylBINAP, TCI B6240 1448897-87-7 (1R,2R)-1,2-Bis(4-methylphenyl)ethylenediamine Dihydrochloride, TCI X0070 137219-86-4 (R)-(+)-XylBINAP, TCI C0347 485-71-2 Cinchonidine, TCI T3153 100165-88-6 (S)-(-)-TolBINAP, TCI C0350 118-10-5 Cinchonine, TCI T3152 99646-28-3 (R)-(+)-TolBINAP, TCI D2729 65283-60-5 (R)-(-)-6,6'-Dibromo-1,1'-bi-2-naphthol.

Selection considers absolute configuration (R or S), salt or free base form, and optical purity (ee), which determine the stereochemical selectivity of reaction products. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
