syntheses of (+)-latrunculin A (1) and (+)-latrunculin B (2), two architecturally novel toxins isolated from the Red Sea sponge Latrunculia magnifica (Keller), have been achieved via highly convergent and stereocontrolled routes (longest linear sequences, 16 and 12 steps, respectively). Formal syntheses of scalemic latrunculins C (3) and M (5) also derive from the construction of 2. Central features of the
(+)-latrunculin A (1) 和 (+)-latrunculin B (2) 的全合成是从红海海绵 Latrunculia magnifica (Keller) 中分离出的两种结构新颖的毒素,已通过高度收敛和立体控制的路线实现。最长的线性序列,分别为 16 和 12 步)。scalemic latrunculins C (3) 和 M (5) 的正式合成也来源于 2 的构建。统一合成策略的核心特征包括醛 (-)-12 与甲基酮 (-)-13 的羟醛反应,a原酸酯 (-)-11 的新型酸催化重组平衡和大环内光信封环化
