Notes:
9α-Hydroxy-19-norandrostenedionc (9α-hydroxy-Δ4-estrene 3, 17-dione) (IV) was prepared by fermentation of 19-norandroslenedione with Corynespora melanis or Norcardia restriclus. When incubated with a growing culture of Arthrobacter simplex or its acetone-dried cells, IV was converted to 9α-hydroxyestronc (VII) and 9-keto-9, 10-secoestrone (VI). 9α-Hydroxyestrone undergoes spontaneous as well as enzymic dehydration to form Δ9(11)-estrone (IX). Both VI and IX have been isolated and identified as such while VII was isolated as its 3-acetate.
