The selective cleavage of carbon-carbon bonds is a significant challenge in synthetic chemistry, yet this strategy can be a powerful way to generate reactive intermediates. We have discovered that, through the facile release of trifluoroacetate which occurs by C-C bond scission, difluoroenolates can be generated under very mild reaction conditions. Unlike existing reactions, this method is not limited
碳-碳键的选择性断裂是合成化学中的一项重大挑战,但这种策略可以成为生成活性中间体的有效方法。我们已经发现,通过 CC 键断裂发生的三氟乙酸盐的轻松释放,可以在非常温和的反应条件下生成二氟烯醇化物。与现有反应不同,该方法不限于一小组氟化结构单元。我们已将此过程应用于羟醛反应以安装二氟亚甲基。
