Dextrans are polysaccharides with molecular weights starting at 1,000 Daltons, consisting of a linear backbone of α-linked D-glucopyranosyl units. Their unique structural properties and versatility make them essential in various biological and medical research applications.
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.
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 ...
Photoredox catalysis has become a powerful synthetic method, which can form Covalent bond under mild reaction conditions through light irradiation.
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 ...
Hydrogenation is a very common reaction in which H2 can be introduced through double or triple bonds and is widely used in both laboratory and industrial production. This reaction usually requires the presence of metal catalysts in order to carry out, in the presence of such catalysts, it is ...
