Our synthetic approach of marine diterpenoids sarcodictyins A and B and eleutherobin relies on the one-step attachment of a C5–C9 side chain at the C10 position. The C1,C10 cis-disubstituted cyclohexene derivative is obtained in 86 % yield with total stereoselectivity. The reaction is based on a syn SE′ process involving a cyclic (Z)-allyl diisopropylcarbamate. (© Wiley-VCH Verlag GmbH & Co. KGaA,
我们合成海洋二萜类 sarcodictyins A 和 B 以及eleutherobin 的方法依赖于 C5-C9 侧链在 C10 位置的一步连接。C1,C10 顺式二取代环己烯衍生物以 86% 的产率获得,具有总立体选择性。该反应基于涉及环状 (Z)-烯丙基二异丙基氨基甲酸酯的 syn SE' 过程。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
