accomplished with a chiral Lewis base and a chiral Brønsted acid as cocatalysts, generating various β-arylthio ketones bearing an all-carbon quaternary center in moderate to excellent yields and excellent enantioselectivities. These chiral arylthio ketone products are common intermediates with many applications, for example, in the design of new chiral catalysts/ligands and the total synthesis of natural products
以手性路易斯碱和手性布朗斯台德酸为助催化剂,完成1,1-二取代和三取代的烯丙醇的对映选择性亚磺基化/ semipinacol重排,生成各种带有全碳季中心的β-芳硫基酮,产率中等至优异。优异的对映选择性。这些手性芳硫基酮产物是常见的中间体,具有许多应用,例如,在新的手性催化剂/配体的设计以及天然产物的总合成中。进行了计算研究(DFT计算)来解释手性布朗斯台德酸的对映选择性和作用。另外,该方法的合成效用以(-)-香叶烯的对映选择性全合成和手性亚砜和砜的一锅法合成为例。
