Description

The chromophores of the chromoprotein antibiotics C-1027, kedarcidin, and maduropeptin feature a unique nine-membered enediyne structure in the ansa-macrolide ring and show extremely potent cytotoxicity. Their complicated fused ring systems were recently synthesized and the total synthesis of (−)-maduropeptin chromophore was achieved, which thereby led to the revision of its stereochemical structure.
