Synthesis of clavulones II (1) and III (2) (claviridenones c and b), antitumor marine prostanoids, has been achieved via [3+2] annulation using reaction of (β-(phenylthio)acryloyl)silane 5 with methyl ketone enolate 6 followed by installation of the α-side chain by aldol reaction.
克拉维酮 II (1) 和 III (2)(claviridenones c 和 b)、抗肿瘤海洋前列腺素类化合物的合成,已通过 (β-(苯硫基)丙烯酰基)硅烷 5 与甲基酮烯醇化物的反应通过 [3+2] 成环实现。 6 随后通过羟醛反应安装α-侧链。
