An efficient palladium-catalyzed oxidative C-C bond forming cascade reaction of allenes involving a coupling between an enallene and an allenyne followed by a carbocyclization of the generated Pd-intermediate was developed. This cascade reaction afforded functionalized cross-conjugated polyenes. The enallene is initially activated by palladium and reacts with the allenyne to give the cross-conjugated polyenes.
开发了一种高效的钯催化丙二烯氧化C-C键形成级联反应，该反应涉及烯丙二烯和烯丙炔之间的偶联，随后生成的钯中间体进行碳环化。这种级联反应提供了功能化的交叉共轭多烯。烯丙二烯首先被钯活化，然后与烯丙炔反应生成交叉共轭多烯。
