CH-acids of general formula CF3CH(X)CF3 (X = CF3, CO2R) react with 2,3-unsaturated alcohols in the presence of bases to give trifluoromethylated products of the [3,3]-sigmatropic rearrangement. These reactions provide a convenient method for the synthesis of 2-alkenyl-2-trifluoromethylmalonates.
通式 CF3CH(X)CF3 (X = CF3, CO2R) 的 CH-酸在碱存在下与 2,3-不饱和醇反应,得到 [3,3]-σ 重排的三氟甲基化产物。这些反应为合成 2-烯基-2-三氟甲基丙二酸酯提供了一种方便的方法。
