Alkaline oxidation of diastereoisomeric 4a,10a-dihydrofusarubins to norjavanicin, fusarubin, and a new antibiotic isofusarubin: nonenzymic formation of products in Fusariumsolani cultures
Abstract Anhydrofusarubin lactol has been isolated from the fungusNectriahaematococca and identified on the basis of its spectral properties, the formation of derivatives and a partial synthesis from fusarubin. Its biological origin is discussed.
