Abstract
A series of phosphine-Pt(2+)-catalysts is reported, which enable the oxidative cascade cyclization of poly-alkene substrates. When the terminus is appropriately arranged and a catalyst reoxidation mediator is included, several polycyclic all carbon skeletons can be obtained. In one example, a chiral P2Pt(+2) catalyst provides up to 79% ee.
摘要
本文报道了一系列膦-Pt(2+)-催化剂，可实现多烯烃底物的氧化级联环化。当适当排列末端并包含催化剂再氧化介体时，可以获得几种多环全碳骨架。在一个例子中，手性 P2Pt(+2)催化剂提供高达 79%的对映体过量。
