are reported. The first generation total synthesisunambiguously confirmed our earlier assignment of the relative and absolutestereochemistry of mycolactones A and B. Knowledge of the chemical properties of the mycolactones accumulated through the first generation total synthesis allowed us to implement several major improvements to the original synthesis, including: (1) optimizing the choice of protecting
报告了支链内酯 A 和 B 的第一代和第二代全合成。第一代全合成明确证实了我们之前对分支杆菌内酯 A 和 B 的相对和绝对立体化学的分配。通过第一代全合成积累的分支杆菌化学性质的知识使我们能够对原始合成进行几项重大改进,包括:(1)优化保护基的选择,(2)消除保护基的不必要调整,(3)提高整体立体选择性和合成效率。第二代全合成由 21 个最长的线性步骤组成,总产率为 8.8%。
