α-Fluorinated acrylates could act as Michael acceptors and become a platform toward the synthesis of relevant complex molecules. Very few conjugate additions have been developed in the literature with these specific substrates, and herein, we reported the first phospha-Michael addition (PMA) on α-trifluoromethylacrylates and α-fluoromethylacrylates. The reaction proved to be highly tolerant and gave original products containing contiguous C-P and C-CFY (Y = F or H) bonds in good to excellent yields and diastereoselectivities.
α-氟代丙烯酸酯可以作为迈克尔受体,并成为合成相关复杂分子的平台。在文献中,用这些特定的底物开发的共轭加成反应很少,在此,我们报道了首例α-三氟甲基丙烯酸酯和α-氟甲基丙烯酸酯的膦迈克尔加成(PMA)反应。该反应具有高度的耐受性,以良好到优秀的收率和非对映选择性得到了含有连续 C-P 和 C-CFY(Y = F 或 H)键的原始产物。
