The C14-C20 unit 11 of the polyene macrolide antibiotic amphotericin B (1) was synthesized from L-arabinose in 13 steps. The key step 7 → 10 features diastereocontrol through asymmetric induction in a novel [23] Wittig rearrangement.
由L-阿拉伯糖以13个步骤合成多烯大环内酯抗生素两性霉素B(1)的C 1 4 -C 20单元11。关键步骤7→10的特点是通过新颖[23]的维蒂格重排中的不对称感应进行非对映控制。
