The first enantioselective total syntheses of cytotoxic macrolide amphidinolide B1 and the proposed structure for amphidinolide B2 have been accomplished. Key features of the syntheses include a diastereoselective aldol condensation, a spontaneous Wadsworth-Emmons macrocyclization and a directed epoxidation/elimination sequence.
细胞毒性大环内酯类多球壳菌素B1的首次对映选择性全合成以及多球壳菌素B2的推定结构已完成。合成的关键特征包括非对映选择性羟醛缩合、自发的沃兹沃思-埃蒙斯大环化反应以及定向环氧化/消除序列。
