Electrogenerated Ni(0) complexes from stable Ni(II) compounds are the catalysts for the electrochemical incorporation of carbon dioxide into carbon-carbon double bonds. Different kind of olefin derivatives have been carboxylated to afford mono- or dicarboxylic acid derivatives depending on the alkene structure. The electrolyses are carried out in one compartment cells fitted with a magnesium anode under mild conditions.

Molecular design and chemicalsynthesis of several palmerolide A analogues allowed the first structure activity relationships (SARs) of this newly discovered marine antitumor agent. From several analogues synthesized and tested (ent- 1, 5- 14, 21- 26, 50, 51), compounds 25 (with a phenyl substituent on the side chain) and 51 (lacking the C-7 hydroxyl group) were the most interesting, exhibiting approximately
几种palmerolide A 类似物的分子设计和化学合成允许这种新发现的海洋抗肿瘤剂的第一个结构活性关系(SAR)。从合成和测试的几个类似物(ent-1、5-14、21-26、50、51)中,化合物 25(在侧链上有苯基取代基)和 51(缺少 C-7 羟基)是最多的有趣的是,与天然产物相比,其效力和等价性分别增加了大约 10 倍。这些发现为更集中的结构活性关系研究指明了方向。
