Title: 12-keto-allopregnane derivatives
Inventor: CALLOW ROBERT KENNETH
IPC: C07J75/00
Filed: 1953-05-04
Abstract: The invention comprises compounds of the formula <FORM:0750799/IV(a)/1> (where R is Br, Cl, I or H, and X is H or an acyl group) and a process for the preparation of a 16 - halo - 17a  - hydroxyallopregnane - 12:20-dione by treating an allopregn-16-ene-12:20-dione with hydrogen peroxide to produce a 16a :17a  - oxidoallopregnane - 12:20 - dione and then splitting the epoxide ring with hydrogen halide.  The halogen atom can be subsequently eliminated by reduction.  In an example allopregn - 16 - en - 3b  - ol - 12:20 - dione acetate in methanol is treated with alkaline hydrogen peroxide, yielding 16a :17a -oxidoallopregnan - 3b - ol - 12:20 - dione acetate, which on treatment with hydrobromic acid in glacial acetic acid furnishes 16-bromoallopregnane-3b :17a  - diol - 12:20 - dione - 3 - acetate.  The free diol is obtained by hydrolysis. Debromination of the above 16-bromoallopregnane acetate by refluxing in ethanol with Raney nickel gives allopregnane - 3b :17a  - diol - 12:20 - dione 3-acetate.
