method for CF3-containing oxazolines via trifluoromethylation of allylamides by using Togni reagent in the presence of alkali metal iodides, which play a key role in selective production of the desired oxazoline. The reaction did not proceed efficiently with copper catalysts commonly used for oxytrifluoromethylations. Our method afforded a wide variety of CF3-containing oxazolines, which are potential candidates
我们报告了一种有效的合成方法,通过在碱金属碘化物的存在下使用Togni试剂通过丙烯酰胺的三氟甲基化丙烯酰胺的三氟甲基化来制备含CF 3的恶唑啉,该方法在选择性生产所需的恶唑啉中起关键作用。用通常用于氧三氟甲基化的铜催化剂不能有效地进行反应。我们的方法提供了多种含CF 3的恶唑啉,它们是药物,农用化学品和功能材料的潜在候选者。
