A formal synthesis of (–)-siccanin was achieved through an enantioselective domino Wacker/carbonylation/methoxylation reaction as the key step to form the chroman ring with a quaternary stereogenic center with 95% ee. The pendant cyclohexyl moiety was introduced through a two-step aldol condensation.
(-)-siccanin 的正式合成是通过对映选择性多米诺瓦克/羰基化/甲氧基化反应实现的,这是形成具有 95% ee 的四元立体中心的色满环的关键步骤。侧环己基部分通过两步羟醛缩合引入。
