such as homeostasis regulators and mechanism‐based enzyme inhibitors. However, it is difficult to control the stereoselectivity of known carbonyl olefination reactions, and olefin metathesis is limited to disubstituted terminal monofluoroalkenes. Although sulfoximines have been used extensively in organic synthesis, reports on their use in carbonyl olefination reactions have not appeared to date. Herein
末端一氟烯烃是生物活性化合物设计中的重要结构基序,例如稳态调节剂和基于机理的酶抑制剂。然而,难以控制已知的羰基烯烃化反应的立体选择性,并且烯烃复分解限于二取代的末端一氟烯烃。尽管亚砜肟已被广泛用于有机合成中,但迄今尚未出现有关其在羰基烯化反应中的使用的报道。在本文中,我们报道了用氟磺酰亚胺试剂进行高度立体选择性的羰基单氟烯烃化反应。MDL 72161的合成以及复杂分子(如氟哌啶醇和类固醇衍生物)的后期单氟甲基化证明了这种方法的潜力。
