The first enantioselective total synthesis of aspergillide C, a cytotoxic 14-membered macrolide isolated from the marine-derived fungus Aspergillus ostianus, has been accomplished from a commercially available chiral glycidol derivative by a 12-step sequence involving an expeditious preparation of a cyclic acetal intermediate and a trans-selective Ferrier-type two-carbon homologation reaction.
曲霉内酯C的首次对映选择性全合成是从海洋来源的真菌曲霉曲霉中分离出的一种具有细胞毒性的14元大环内酯,它是通过市售的手性缩水甘油衍生物通过12步序列完成的,涉及快速制备环状缩醛中间体以及反式Ferrier型两碳同源反应。
