The synthesis of a diastereomer of lytophilippine A required 22 longest linear steps using known building blocks. Cross-metathesis/asymmetric aldol addition and regioselective esterification/ring-closing metathesis served as efficient combi tools for scaffold construction. Detailed NMR investigations in different solvent (systems) provide evidence for a deep-seated configurational misassignment of
冻干品A的非对映异构体的合成需要使用已知构件的22个最长的线性步骤。交叉复分解/不对称醛醇加成和区域选择性酯化/闭环复分解是构建支架的有效组合工具。在不同溶剂(系统)中进行的详细NMR研究为名为lytophilippine A的分子的根深蒂固的构型错配提供了证据。
