Cabaj, John E.; Kairys, David; Benson, Thomas R. published the artcile< Development of a Commercial Process to Produce Oxandrolone>, Related Products of 112-63-0, the main research area is Oxandrolone preparation.
A manufacturing scale process for the preparation of the anabolic steroid Oxandrolone was developed. Key elements included the following: the bromination of methylandrostanolone with perbromide to give the 2-bromoketone in ca. 80% yield with minimal dehydration, subsequent elimination of the bromide with Li2CO3/LiBr to give the 2-enone in ca. 70% yield with minimal formation of methyltestosterone, and an ozonolysis procedure to give the penultimate intermediate in ca. 90% yield. The overall yield from methylandrostanolone to Oxandrolone using the described process was 45% as compared to the original Searle yield of 8%.
Organic Process Research & Development published new progress about Bromination. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Related Products of 112-63-0.
