modifying theA ring has been developed. It is established that the yields of the main and the side products greatly depend on the transformation conditions, mycelium age, and the structure of the steroid substrate. Under the optimal transformation conditions novel 9α-hydroxysubstituted derivatives of androstenolone, pregnenolone, 16-dehydro-16α,17α-epoxy-, and-16α-methoxypregnenolone have been obtained
