The synthesis of a C1 reduced form of the C1–C11 fragment of peloruside B has been achieved in 15 synthetic steps. The strategy involved the use of D-tartaric acid to set the absolute stereochemistry and a 1,5-anti Mukiayama aldol reaction. Analog synthesis of C8–C11 is also reported, which enables changes at the C10 position of peloruside B to be made. The synthesis of the fragment concludes with
peloruside B 的 C1-C11 片段的 C1 还原形式的合成已在 15 个合成步骤中实现。该策略涉及使用 D-酒石酸来设置绝对立体化学和 1,5-抗 Mukiayama 羟醛反应。还报告了 C8-C11 的模拟合成,这使得 peloruside B 的 C10 位置发生变化。片段的合成以受保护的醇状态而不是天然酯的 C1 结束。
