An asymmetric total synthesis of trilobacin (1), an annonaceous acetogenin with potent anticancer activities, was accomplished wherein the construction of its erythro-bis(2,2')-tetrahydrofuran core 2 featured a novel organoselenium-mediated oxonium ion formation/SiO(2)-promoted fragmentation of alpha,alpha'-cis-oxocene 3.
完成了三叶菌素 (1) 的不对称全合成,这是一种具有强效抗癌活性的番荔枝素,其中红-双 (2,2')-四氢呋喃核心 2 的构建具有新型有机硒介导的氧鎓离子形成/SiO( 2)-促进 alpha,alpha'-cis-oxocene 3 的片段化。
