A new practical route for the first total synthesis of (+)-homopumiliotoxin 223G is described, in which the palladium-catalyzed carbonylation of the vinyl iodide, leading to efficient construction of the quinolizidine nucleus incorporating the (Z)-alkylidene side chain, is the key strategic element. Another key feature of this synthesis involves the Lewis acid-induced chelation-controlled propargylation
描述了一种首次完全合成(+)-全铝毒素223G的新的实用途径,其中钯催化的碘代乙烯羰基化反应有效地构建了掺入(Z)-亚烷基侧链的喹oli嗪核。关键的战略要素。该合成的另一个关键特征涉及使用具有完全非对映选择性的烯丙基硅烷进行的路易斯酸诱导的螯合控制的炔丙基化。
