The two marine natural products rubrolide R (1) and S (2) were synthesised in only three linear steps starting from commercially available tetronic acid without using protecting-group chemistry. Key steps in the syntheses were the Pd-catalysed Suzuki–Miyaura cross-coupling followed by a vinylogous aldol condensation. Both compounds have been tested for their antibiotic and antiviral activities. At
两种海洋天然产物 rubrolide R (1) 和 S (2) 仅通过三个线性步骤从市售的特电子酸开始合成,不使用保护基化学。合成中的关键步骤是 Pd 催化的 Suzuki-Miyaura 交叉偶联,然后是乙烯基羟醛缩合。两种化合物均已测试其抗生素和抗病毒活性。在 10 µm rubrolide R (1) 和 S (2) 的浓度下,检测到季节性流感病毒 (H3N2) 和大流行猪流感病毒 (pH1N1) 的病毒滴度降低了 2-log 和 1.5-log,分别。
