Abstract
During the transformation of I, the expected ll=-hydroxy-androst-4-ene-3, 17-dione (IV) was formed in a small amount. As the main product, a compound was isolated by crystallization, which, according to the IR spectral data, has two hydroxylic groups (3440 and 3320 cm-l) and does not contain a carbonyl group in the five-membered ring. It has been concluded from these data that the Beauveria sp. fungus not only brings about ll~-hydroxylation, but ...
