Circumdatins D, E, and F: Further Fungal Benzodiazepine Analogues from <i>Aspergillus </i><i>ochraceus</i>

Abstract

Three new benzodiazepine alkaloids belonging to the circumdatin series have been isolated as minor constituents of culture extracts of a terrestrial strain of the fungus Aspergillus ochraceus. Their structures were solved by MS and NMR comparison with previously reported circumdatin analogues.
