An intramolecular Heck reaction (90 → 91) serves as the key step in the total synthesis of the titled compounds. The synthetic route is based on utilizing the Wieland−Miescher ketone (5) as a matrix to provide the C and D rings of the targets and to provide functionality implements for joining this sector to an A ring precursor (6). Catalytically induced enantiotopic control and early emplacement of
分子内 Heck 反应 (90 → 91) 是标题化合物全合成的关键步骤。合成路线基于利用 Wieland-Miescher 酮 (5) 作为基质来提供目标的 C 和 D 环,并提供将该部分连接到 A 环前体 (6) 的功能性工具。催化诱导的对映体控制和氧杂环丁烷的早期置换是该路线的其他特征。
