The first enantioselective total synthesis of a polyhydroxylated macrolide, (+)-seimatopolide A, was achieved. The key reactions, Sharpless asymmetric dihydroxylation, Yamaguchi esterification, and ring-closing metathesis, provided easy access to the target molecule from L-aspartic acid. Further, the absolute stereochemistry of the natural product has also been revised.
实现了多羟基化大环内酯 (+)-seimatopolide A 的第一个对映选择性全合成。关键反应 Sharpless 不对称二羟基化、Yamaguchi 酯化和闭环复分解为从 L-天冬氨酸中获得目标分子提供了便利。此外,还修订了天然产物的绝对立体化学。
