With rapid advances in the field of cross-coupling reactions of unactivated substrates catalyzed by metal complexes, the chemical market has been revolutionized by the introduction of a large library of achiral and chiral phosphine ligand compounds. Phosphine ligands have shown positive effects ...
Although the Markovian rule plays a key role in explaining the mechanism of olefin Addition reaction, and it has also been widely used in scientific research and practical production, there are very few kinds of addition products with anti Markovian rules obtained through catalytic processes.
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 ...
The photoreaction undergoes a special molecular transformation to form a product that is not obtained through a thermal reaction. In recent years, the light reaction induced by visible light has been further developed. The light reaction in visible light does not require high-energy ultraviolet ...
C(sp2)- and C(sp)-hybridized coupling reactions are established catalytic approaches. However, multi-step C(sp3)- and C(sp2)-coupling reactions of boronic acids and related derivatives are still limited by ineffective two-electron transmetalation reactions. These conventional protocols exhibit ...
Asymmetric organocatalysis has emerged as a powerful synthetic tool that is complementary to metal-catalyzed reactions. Pioneering work in this area dates back to the 1970s in which Eder et al. and Hajos et al. separately reported an intramolecular asymmetric aldol reaction which employed ...
In recent years, asymmetric organic catalytic processes have increasingly become more mature and have been utilized in practical application scenarios.In comparison to metal catalytic processes, organic amine catalysts present numerous potential advantages, such as a more stable physicochemical ...
Since the first proline-catalyzed asymmetric synthesis was reported in 1971, a number of asymmetric syntheses using proline and derivatives have been developed. Proline-type organocatalysts are predominantly applicable to a wide assortment of asymmetric aldol reactions and asymmetric ...
Recently, environmentally friendly oxidation reactions catalyzed by a nitrogen-oxygen radical, TEMPO, have attracted attention. Iwabuchi et al. reported that a nitrogen-oxygen radical, 2-azadamantane-N-oxygen (AZADO), efficiently catalyzed oxidation reaction of alcohols.
