Digitoxigenin ( 3 ) was transformed by a Fusarium spec. to 7β‐hydroxydigitoxigenin ( 1 ) 1β, 7β‐dihydroxydigitoxigenin ( 4 ) and to the hitherto unknown 7β, 11α‐dihydroxydigitoxigenin ( 9 ). 7β‐acetoxy‐digitoxigenin ( 2 ) was degraded to methyl 3β, 7β‐diacetoxy‐14‐hydroxy‐5β, 14β, 17αH‐etianate ( 11 ).
