γ-arylation of substituted silyl-activated butenolides has been studied using a broad scope of unsymmetrical hypervalent diaryliodonium salts via a palladium- or copper-catalysed coupling reaction, yielding interesting reactivity trends. The mild catalytic conditions and coupling partner variability provide access to synthetically useful building blocks toward the pursuit of aryl-lactone containing
已经通过钯或铜催化的偶合反应,使用各种不对称的高价二芳基碘鎓盐,对取代的甲硅烷基活化的丁烯内酯的γ-芳基化进行了研究,产生了有趣的反应趋势。温和的催化条件和偶联配偶体的可变性为寻求含芳基内酯的天然产物提供了合成上有用的组成部分,并实现了多样化。
