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 Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3SDS of cas: 139139-80-3).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.SDS of cas: 139139-80-3
