Azastene is a chemical that modulates 3β-hydroxysteroid dehydrogenase activity.^[1]

Synthesis

Azastene synthesis:^[2]

One synthesis of this compound involves initial alkylation of methyl testosterone by means of strong base and methyl iodide to afford the 4,4-dimethyl derivative. Formylation with alkoxide and methyl formate leads to the 2-hydroxymethyl derivative. Reaction of this last with hydroxylamine leads to formation of an isoxazole ring. There is then obtained azastene.
