The total synthesis of neoaltenuene, a toxin produced by alternaria fungi, has been achieved for the first time in 14 steps in a yield of 10 % starting from quinic acid and phloroglucinic acid, the longest linear sequence consisting of 10 steps. The key reaction was a palladium-catalyzed Suzuki-type coupling of an arene boronate with an iodinated cyclohexene.4a-epi-Neoaltenuene, a non-natural isomer
由链格孢属真菌产生的毒素新烯烃的全合成首次以奎尼酸和间苯三甲酸为起始原料,分 14 步完成,产率为 10%,最长的线性序列由 10 步组成。关键反应是钯催化的芳烃硼酸酯与碘化环己烯的 Suzuki 型偶联。4a-epi-Neoaltenuene,一种非天然异构体也已类似地合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
