    摘要:
    已经合成了新型的氧杂蒽酮螺环供体,并通过使用1,3,5-三甲氧基苯和1,3-二甲氧基苯的umpolung S-芳基化策略进行活化。讨论了所得的2,4,6-三甲氧基苯基(TMP)-和2,4-二甲氧基苯基(DMP)-氧杂蒽基螺酮tal离子的比较反应性,并将它们在糖基化反应中的α-立体选择性与类似的TMP-衍生自带有甲基缩酮基的氧杂蒽基糖基供体的DMP-离子。结果表明,氧杂蒽基糖基供体的立体选择性取决于缩酮基的结构,并且可以通过改变sulf离子上的取代基来调节反应性。

    The discovery of distinct modes of asymmetric catalysis has the potential to rapidly advance chemists' ability to build enantioenriched molecules. As an example, the use of chiral cation salts as phase-transfer catalysts for anionic reagents has enabled a vast set of enantioselective transformations. A largely overlooked analogous mechanism wherein a chiral anionic catalyst brings a cationic species into solution is itself a powerful method. The concept is broadly applicable to a number of different reaction pathways, including to the enantioselective fluorocyclization of olefins, and dearomatization of aromatic systems with a cationic electrophile-transferring (e.g., fluorinating) agent and a chiral phosphate catalyst. The reactions proceed in high yield and stereoselectivity. The compounds and methods of the invention are of particular value, especially considering the scarcity of alternative approaches.
    发现不对称催化的不同模式具有潜力快速推动化学家构建手性富集分子的能力。例如,使用手性阳离子盐作为相转移催化剂用于阴离子试剂已经实现了大量手性选择性转化。一个被大多数人忽视的类似机制是手性阴离子催化剂将阳离子物种溶解到溶液中,这本身就是一种强大的方法。这一概念广泛适用于许多不同的反应途径,包括对烯烃进行手性选择性氟环化和用阳离子亲电试剂转移(例如,氟化)剂和手性磷酸盐催化剂进行芳香系统去芳构化。这些反应产率高,立体选择性好。该发明的化合物和方法具有特殊价值,尤其考虑到替代方法的稀缺性。
