Visible light-induced photoreactions have been intensively developed, because a photoreaction under visible light does not require high energy UV light and the reactions occur under mild conditions to avoid forming unexpected by-products. TCI offers many organocatalysts and metal complex catalysts like ruthenium and iridium-based complexes for the photoreactions. It has been reported that the photoredox catalysts catalyzes Csp2-Csp3 bond formation, which is difficult to achieve with palladium catalysts. And they are used as photoactivated co-catalysts for nickel-catalyzed ligand-free aryl amination.
Chiral Auxiliary for the Synthesis of Optically Active Amino Acids
(S)-N-(2-Benzoylphenyl)-1-benzylpyrrolidine-2-carboxamide [B5519] is a chiral auxiliary agent used in the synthesis of optically active amino acids. When racemic α-amino acids substrates react with B5519 in the presence of nickel nitrate and sodium methoxide, the isomerization at the α-position of the amino acids occurs via the formation of an intermediate. The hydrolysis of the intermediate by acid, yields (S)-amino acids with high optical purity.
TCI Practical Example: β-Lactamization through Condensation Reaction
We are proud to present the condensation reaction using 2,2'-dipyridyl disulfide [D1114] and triphenylphosphine [T0519] for the formation of β-lactams. The reaction report is actually performed by TCI's synthesis staff. You can see not only the reaction procedure but also the comment and analysis data from our staff.
TCI Practical Example: Olefin Metathesis with AquaMet
TCI introduces the cyclopentene ring formation via olefin metathesis using AquaMet [A3009] as a catalyst. AquaMet has a powerful activity of catalytic reaction same as conventional metathesis catalysts.
