9α-hydroxy-17-keto steroids are prepared by fermenting steroids having a C-17 side chain of 5-10 carbon atoms inclusive, with the novel Mycobacterium species CBS 482.86.
Starting from various substrates containing a 5-10 C carbon chain an C-17, 9α-hydroxyandrost-4-ene-3,17-dione, 7α,9α,12α-trihydroxyandrost-4-ene-3,17-dione or 9α-hydroxyandrost-4,11-diene-3,17-dione are obtained in high yield.
The resulting compounds are useful intermediates in the synthesis of therapeutically important steroids, particularly corticosteroids.
新型分枝杆菌 CBS 482.86 通过发酵具有 5-10 个碳原子的 C-17 侧链的类固醇,制备出 9α-羟基-17-酮类固醇。
从含有 5-10 个碳原子的 C-17 侧链的各种底物开始,可以高产率地获得 9α-羟基雄甾-4-烯-3,17-二酮、7α,9α,12α-三羟基雄甾-4-烯-3,17-二酮或 9α-羟基雄甾-4,11-二烯-3,17-二酮。
所得化合物是合成具有重要治疗作用的类固醇,特别是皮质类固醇的有用中间体。
