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。

promote intramolecular conjugate additions of alkyl halides onto alpha,beta-unsaturated lactones. This process has been shown to be applicable to a number of alpha,beta-unsaturated lactones, including tetrasubstituted olefins, and has been demonstrated to be quite general for the formation of saturated bicyclic and tricyclic lactones. The method presented herein provides a mild, efficient process to form

The intramolecular cycloaddition reactions of non-stabilised azomethine ylides generated by condensation of 4-(3-propanalyl)-5-methylene-2(5H)furanone and cyclic amino acids were investigated. The reactions proceeded via highly stereoselective formation of anti- dipoles followed by cycloaddition reactions on either the α,β- or γ,δ- double bond to produce polycyclic cycloadducts in good yield. Both

Catalysed cross-coupling of butenolide-3-triflates to 9-alkyl-9-borobicyclo[3.3.1]nonanes occurs in moderate to good yield and tolerates a range of functionality. Application of this methodology combined with addition of diethylzinc to a butenolide aldehyde in the presence of an ephedrine derivative leads to a 3-step synthesis of (−)-isoseiridine with 88%e.e. in good yield.
