LL-Z1220 is a novel antibiotic with the structure of 2-(3,8-dioxopentacyclo[5.1.0.0^~^~]oct-5-en-5-yl)-4H-pyran-4-one. This appears to be the first reported natural product containing a benzene dioxide group. This antibiotic readily undergoes valence isomerization to form 1,4-dioxopentacyclo. The chemical and spectroscopic properties of the antibiotic suggest that the benzene dioxide has a cis configuration.
