A nitrogen-centered radical strategy for the preparation of 3-acylated spiro[4,5]trienones I [R1 = H, 6-Me, 7-I, etc.; R2 = Me, Bn, allyl, etc.; R3 = Ph, 2-MeC6H4, 2-naphthyl, etc.; R4 = Me, Et, iPr, etc.] via visible-light-mediated acylation/ipso-cyclization of alkynes with acyl oxime esters was reported. This method provided a way for the construction of compounds I, which could introduced aryl- or alkyl-substituted acyl into spiro[4,5]trienone skeletons. In addition to this study using fac-Tris(2-phenylpyridine)iridium, there are many other studies that have used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Category: pyridine-derivatives) was used in this study.
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridines, quinolines, and isoquinolines have found a function in almost all aspects of organic chemistry. Pyridine has found use as a solvent, base, ligand, functional group, and molecular scaffold. As structural elements, these moieties are potent electron-deficient groups, metal-directing functionalities, fluorophores, and medicinally important pharmacophores. Category: pyridine-derivatives
