aldehydes and ketones in moderate to good yields. In contrast, alkenyl triflates were not suitable partners for this reaction. This method allowed the preparation of open-chain analogues of the musk odorant Vulcanolide, several of which retained key olfactory properties of the parent molecule.
未活化的烯基碘化物和溴化物与一系列不同链长的烯醇进行了前所未有的钯催化中继-赫克交叉偶联,将烯烃和醇连接起来,以中等至良好的产率提供不饱和醛和酮。相比之下,烯基三氟甲磺酸酯不是该反应的合适伙伴。这种方法允许制备麝香气味剂 Vulcanolide 的开链类似物,其中一些保留了母体分子的关键嗅觉特性。
