摘要:
The invention disclosed herein relates to the process in which an 11-desoxy-3-oxygenated - Delta 4-steroid is subjected to the action of Bacillus cereus microorganisms thereby effecting simultaneous oxygenation (i.e., 11-hydroxylation) and Delta 1dehydrogenation of the steroid to produce an 11 Beta -hydroxy-3oxygenated- Delta 1,4steroid. For example, the 11-desoxy-3oxygenated- Delta 4steroid, Compound S, is converted directly by this microbiological oxygenation-dehydrogenation procedure to its 11 Beta -hydroxy- Delta 1-dehydro analog, prednisolone, which is known to be useful as an anti-inflammatory agent.
