Dianabol 8R,9S,10S,13S,14S,17S-17-hydroxy-10,13
Metandienone (also known as Dianabol)
A synthetic anabolic‑steroid derived from testosterone, introduced in the 1960s for https://gratisafhalen.be/author/jefferywomb medical use and later popularized for bodybuilding. It promotes protein synthesis, nitrogen retention, and lean muscle mass while also increasing red blood cell production.

Synthesis

Starting material – Testosterone (or a suitable analog). Oxidation of C‑17β – Conversion to 17‑oxo‑testosterone using an oxidizing agent such as chromic acid or PCC. Introduction of the methyl group at C‑19 – Methylation with a suitable alkylating reagent (e.g., methyl iodide) under basic conditions. Alkylation at C‑17α – Methylation at the 17α position using a methylating agent like methyl iodide in the presence of a base such as NaH or LDA. Final purification – Chromatographic separation and recrystallization to obtain pure compound.

The overall synthetic route yields a steroid with both 19‑methyl and 17α‑methyl groups, consistent with the predicted structure.")
