Pisella, Guillaume published the artcileCopper-Catalyzed Oxyvinylation of Diazo Compounds, Synthetic Route of 517-23-7, the publication is Organic Letters (2020), 22(10), 3884-3889, database is CAplus and MEDLINE.
A copper(I)-catalyzed vinylation of diazo compounds with vinylbenziodoxolone reagents (VBX) as partners was reported. The transformation tolerated diverse functionalities on both reagents delivering polyfunctionalized vinylated products. The strategy was successfully extended to a three-component/intermol. version with alcs. The obtained products contain synthetically versatile functional groups, such as an aryl iodide, an ester, and an allylic leaving group, enabling further modification.
