1,150,955. 11#-Hydroxylation of steroids. KONINKLIJKE NEDERLANDSCHE. GISTEN SPIRITUSFABRIEK N.V. 25 April; 1967 [25 April, 1966], No. 18937/67. Heading C2U. 11#, 17α-Dihydroxy steroids are prepared by oxygenation of 11-unsubstituted-17α- (esterified or etherified hydroxy)-steroids with the aid of enzymes from fungi of the Curvularia genus. If the 17-etherifying or esterifying group survives this reaction, then a subsequent hydrolysis is necessary. |
