Pharmacology

Oxandrolone is a synthetic, anabolic steroid hormone analog of testosterone. Similar to testosterone, oxandrolone binds to and activates specific nuclear receptors. This agent may be used for testosterone replacement therapy in hypogonadal men, in HIV-wasting syndrome, and in other conditions in order to increase nitrogen retention and fat-free muscle mass. (NCI04)

How it is made

Pappo, US 3128283 (1964 to Searle)

Methyldihydrotesterone is converted into corresponding 1,2-dehydro compound by bromination followed by dehydrobromination. Ring a is then ruptured through ozonization & subsequent hydrolysis to yield aldehyde-acid. Reduction of formyl group ... yields expected hydroxy acid ...which is lactonized to oxandrolone.
