Total Synthesis of (+)‐Seimatopolide A
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.
