Zusammenfassung

Während unserer Untersuchungen über die mikrobiologische Dehydrierung verschiedener 16β-Methylsteroide durch Bakterienkulturen vonCorynebacterium simplex, wurde eine neue Art von Umwandlung beobachtet. Von 16β-Methyl-Δ9(11)-pregnen-17α, 21-diol-3, 20-dion-21-acetat ausgehend, gelang es aus den Kulturfiltraten 16β-Methyl-Δ1, 4-pregnadien-9α, 11α-epoxy-17α, 21-diol-3, 20-dion zu isolieren. In einigen Fällen wurde auch dasΔ4-Derivat dieser Verbindung als Nebenprodukt erhalten.
