3-(furan-2-yl)propenoic acids and their esters with arenes in Brønsted superacid TfOH affords products of hydroarylation of the carbon–carbon double bond, 3-aryl-3-(furan-2-yl)propenoic acid derivatives. According to NMR and DFT studies, the corresponding O,C-diprotonated forms of the starting furan acids and esters should be reactive electrophilic species in these transformations. Starting compounds and
3-(furan-2-yl) 丙烯酸及其酯与芳烃在 Brønsted 超强酸 TfOH 中的反应提供碳-碳双键 3-aryl-3-(furan-2-yl)propenoic acid 衍生物的氢化芳基化产物. 根据 NMR 和 DFT 研究,起始呋喃酸和酯的相应 O,C-二质子化形式在这些转化中应该是反应性亲电物质。起始化合物及其加氢芳基化产物的浓度为 64 µg/mL,对酵母样真菌白色念珠菌表现出良好的抗菌活性。除此之外,这些化合物还抑制大肠杆菌和金黄色葡萄球菌。
