Significance

Sorangicin A inhibits RNA polymerase in E. coli and S. aureus without affecting eukaryotic cells. It is also active against rifampicin-resistant mutants. The Smith group accomplished the first total synthesis of (+)-sorangicin A which includes the construction of the highly sensitive (Z,Z,E)-trienoate linkage in E via Stille coupling.
