Chan, Hwai-Chien; Bueno, Bianca; Le Roch, Adrien; Gagnon, Alexandre published the article 《Copper-promoted N-arylation of the imidazole side chain of protected histidine by using triarylbismuth reagents》. Keywords: dipeptide arylated histidine synthesis functional group; histidine imidazole arylation copper catalyst triarylbismuth reagent; arylation reaction mechanism; N-arylation; copper catalysis; histidine; imidazole; organobismuthines.They researched the compound: H-Trp-OMe.HCl( cas:7524-52-9 ).SDS of cas: 7524-52-9. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:7524-52-9) here.
The N-arylation of the side chain of histidine by using triarylbismuthines is reported. The reaction is promoted by copper(II) acetate in dichloromethane at 40°C under oxygen in the presence of diisopropylethylamine and 1,10-phenanthroline and allows the transfer of aryl groups with substituents at any position of the aromatic ring. The reaction shows excellent functional group tolerance and is applicable to dipeptides where the histidine is located at the N terminus. A histidine-guided backbone N-H arylation was observed in dipeptides where the histidine occupies the C terminus.
Although many compounds look similar to this compound(7524-52-9)SDS of cas: 7524-52-9, numerous studies have shown that this compound(SMILES:N[C@@H](CC1=CNC2=CC=CC=C12)C(OC)=O.[H]Cl), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
