Technology Process of Pregn-4-ene-3,20-dione,16-hydroxy-, (9b,10a,16a)- (9CI)

There total 2 articles about Pregn-4-ene-3,20-dione,16-hydroxy-, (9b,10a,16a)- (9CI) which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

Progesterone (57-83-0) → 21-Hydroxyprogesterone (64-85-7) + Cortexolone (152-58-9) + 16β-hydroxyprogesterone (17779-71-4,438-07-3,2781-78-4,14264-44-9) + 2beta-Hydroxyprogesterone (604-29-5,604-28-4,123287-83-2)

Guidance literature:

With Bacillus megaterium cytochrome P₄₅₀ BM₃ monooxygenase (R₄₇Y/T₄₉F/V₇₈T/A₈₂F/F₇₈A)-expressing cells; at 25 ℃; for 24h; diastereoselective reaction;
