The article conveys some information:
A fac-Ir(ppy)3-catalyzed intermol. dearomative cyclization of 2-bromo-2-((5-bromofuran-2-yl)methyl)malonate and alkynes affording substituted spirolactones, e.g. I, in yields of 19-91% via a 5-exo-dig radical cyclization under visible light is presented. This method provides a new access to the synthesis of spirocycle skeletons applying water as an external oxygen source under mild reaction conditions. In the experiment, the researchers used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Recommanded Product: fac-Tris(2-phenylpyridine)iridium)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Recommanded Product: fac-Tris(2-phenylpyridine)iridium
