Asymmetric phase transfer catalysis (PTC) is now widely used as a "green" alternative route to numerous homogeneous synthesizer transformations as well. The typical chiral organocatalyst for asymmetric phase transfer catalysis is the synthesis of modified cinchona alkaloids. Several generations ...
Aladdin offers the isothiourea organocatalyst homobenzotetramisole (HBTM) as part of our asymmetric catalysis portfolio in both (R, item number: B120975) and (S, item number: B120963) enantiomeric forms. These compounds have been widely used for enantioselective conversion and kinetic resolution ...
Professor Zhang Junliang's research group from Fudan University has developed 12 series of chiral tert-butylsulfinamide phosphine ligands/catalysts (Sulfinamide Phosphine, collectively referred to as SadPhos) based on the design concept of non-C2 symmetry, combining rigidity and flexibility, as ...
