Synthesis of a 4-Azasteroid Hormones Compound

The document detailed a synthetic process for creating a 4-azasteroid hormone compound, specifically Finasteride. The synthesis involved multiple chemical reactions starting with Pregnadienolone acetate, which was transformed through a series of steps including oxidation, esterification, and ring closure. The final step involved dehydrogenation of the A-ring to produce Finasteride.
