triazolium salt precatalyst has been developed that efficiently promotes the asymmetric intermolecular Stetter reaction of enolizable aldehydes and nitrostyrenes (see scheme). Trans fluorination of the catalyst architecture results in unparalleled reactivity and enantioselectivity in the desired transformation. A DFT study provides evidence of an electrostatic interaction as the source of the increased
氟有帮助:我们开发了一种氟化三唑盐预催化剂,可有效促进烯醇化醛和硝基苯乙烯的不对称分子间Stetter反应(参见方案)。催化剂结构的反式氟化在所需的转化中产生无与伦比的反应活性和对映选择性。 DFT 研究提供了静电相互作用作为对映体感应增加的来源的证据。
