Synthesis of 4-arylcoumarins via palladium-catalyzed arylation/cyclization of ortho-hydroxylcinnamates with diaryliodonium salts was written by Yang, Yang;Han, Jianwei;Wu, Xunshen;Xu, Shujia;Wang, Limin. And the article was included in Tetrahedron Letters in 2015.SDS of cas: 1204518-02-4 The following contents are mentioned in the article:
The palladium-catalyzed arylation/cyclization of ortho-hydroxylcinnamate ester derivatives by using diaryliodonium(III) salts was developed. With this method, 4-arylcoumarins were easily prepared in good to excellent yields under base-free conditions. Addnl., this protocol provided an efficient alternative for the preparation of related 4-arylated coumarin compounds which are useful in the access to 5-lipoxygenase inhibitors. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4SDS of cas: 1204518-02-4).
Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4) belongs to iodide derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.SDS of cas: 1204518-02-4
