and highly stereocontrolled total synthesis of the cytotoxic macrolide (+)-superstolide A is described. Key features of this synthesis include the use of bimetallic linchpin 36b for uniting the C(1)-C(15) (43) and the C(20)-C(27) (38) fragments of the natural product, a late-stage Suzuki macrocyclization of 49, and a highly diastereoselective transannular Diels-Alder reaction of macrocyclic octaene 4
描述了一种细胞毒性大环内酯(+)-超环内酯A的融合和高度立体控制的总合成。该合成的关键特征包括使用双金属针脚36b结合天然产物的C(1)-C(15)(43)和C(20)-C(27)(38)片段, Suzuki 49的大环化阶段,以及大环辛烯4的高度非对映选择性的跨环Diels-Alder反应。相反,五烯醛5的分子内Diels-Alder反应提供了所需的具有较低立体选择性(6:1:1)的环加合物。
