The formation of the dihydrobisfuran ring system uniquely representative of the aflatoxins among polyketide natural products is achieved in three net oxidative steps relating averufin (2) to versicolorin A (5). The first of these oxidativerearrangements carries the former to 1'-hydroxyversicolorone (3). Labeling experiments have placed several limitations on the mechanisms of reactions that can account
