A vanadium-catalyzed method for the oxidation of prochiral aryl, allylic selenides with tandem [2,3] sigmatropic rearrangement has been developed. This protocol has been screened on a series of substrates to test for its generality and effectiveness. The applicability of this methodology to the synthesis of enantiomerically enriched allylic alcohols has been studied on a series of chiral oxazole-containing
已经开发出了一种钒催化的具有串联[2,3]σ重排的前手性芳基烯丙基硒化物的氧化方法。该协议已在一系列底物上进行筛选,以测试其通用性和有效性。已经在一系列手性恶唑含量高达85:15的非对映体比率的体系中研究了该方法在对映体富集的烯丙醇合成中的适用性。在烯丙醇产品中观察到的手性转移是净感应1,9和/或1,10感应的结果。最后,似乎已经通过X射线晶体分析观察到了在含恶唑的硒化物中硒-氧非键相互作用的第一个例子。
