Abstract

Cyclopentanophenanthrene compounds having a methylene group in the nucleus at the 11-position, e.g. cortical steroid type compounds having a methylene group at the 11-position, are 11b -hydroxylated by the action of oxygenating substances produced by growing a microorganism of the species Curvularia lunata. The cyclopentanophenanthrene reactant may be subjected to the action of a growing culture of the micro-organism, or the micro-organism may be cultivated aerobically in a nutrient medium until substantial growth is obtained, the mycelium is separated from the broth and the cyclopentanophenanthrene reactant is then contacted with an aqueous suspension of the mycelium. Cyclopentanophenanthrene reactants may have a keto or hydroxy group at the 3-position, a 21-hydroxy group and carbon to carbon double bonds in the nucleus, e.g. at the 3,4- or 5,6-position. Specified reactants are progesterone, D 4 - pregnene - 17a - ol - 3,20-dione, testosterone, D 4 - androstene - 3,17-dione and D 1,4 - pregnadiene - 17a ,21 - diol-3,20-dione. In the examples compound F (17 - hydroxy - corticosterone) is prepared from compound S (17 - hydroxy - 11 - desoxycorticosterone), and corticosterone is prepared from 11-desoxycorticosterone; in each case an aqueous nutrient medium is used.
