Compounds of the formula ##STR1## are inhibitors of 5.alpha.-reductase and are useful alone or in combination with other active agents for the treatment of hyperandrogenic disorders such as acne vulgaris, seborrhea, female hirsutism, male pattern baldness, and benign prostatic hyperplasia.
Compounds of the Formula I ##STR1## are inhibitors of the 5.alpha.-reductase 1 isozyme, and are useful alone, or in combination with a 5.alpha.-reductase 2 inhibitor, for the treatment of androgenic sensitive disorders such as acne vulgaris, seborrhea, female hirsutism, male pattern baldness, and benign prostatic hyperplasia.

Described is a new process for producing 7.beta.-substituted-4-aza-5.alpha.-androstan-3-ones and related compounds which are 5.alpha.-reductase inhibitors, consisting of reducing the corresponding androsteneone with lithium and liquid ammonia, contacting the product with an isomerizing agent, oxidizing the product to a seco acid and reacting that seco acid with an amine to cyclize to form 4-aza-5.alpha.-androstan-3-ones.
