antitumor agents are currently in phase II clinical trials for the treatment of a variety of forms of cancer. Aldol reactions and directed reductions are among the essential steps for the formation of fragments A-C in the total synthesis of the title compound. Coupling of these fragments by sulfone-based olefination and alkylation reactions was followed by macrocyclization and introduction of the enoate moieties
高效的抑菌素抗肿瘤药目前处于II期临床试验中,用于治疗多种形式的癌症。醛醇缩合反应和直接还原反应是标题化合物总合成中形成片段AC的重要步骤。通过基于砜的烯化和烷基化反应偶联这些片段,然后进行大环化并在环B和C上引入烯酸酯部分。
