The total syntheses of cyclic nitrone-containing phlegmarine-type Lycopodium alkaloids, lycoposerramines-X and -Z, were accomplished starting from (R)-3-methylcyclohexanone via Pd-catalyzed Suzuki−Miyaura coupling, Johnson−Claisen rearrangement, stereoselective hydroboration−oxidation reaction, and Mitsunobu reaction, thereby establishing the structures including the absolute configuration.
含有环状硝酮phlegmarine型的全合成石松生物碱,lycoposerramines-X和-Z,分别实现了从(起始- [R)-3-甲基环己酮通过Pd-催化的Suzuki-Miyaura偶联,约翰逊-Claisen重排,立体选择性硼氢化-氧化反应和光延反应,从而建立了包括绝对构型在内的结构。
