Title: Improvements in or relating to steroids and the production thereof
IPC: C07J75/00
Filed: 1952-09-02
Abstract: The invention comprises 3-hydroxy-8(9)-unsaturated - 11,14 - dihydroxylated steroids (and the 3-esters and 3-ethers thereof) having an unsaturated aliphatic hydrocarbon radical at the 17-position, and the corresponding compounds containing unsaturated bonds in the 6(7) and 8(9) positions, and a process for the selective reduction of a 3-hydroxy-8(9)-unsaturated-11,14-peroxide containing an unsaturated aliphatic hydrocarbon radical at the 17-position, or an ester or ether thereof, to form an 8(9)-unsaturated-11,14-dihydroxylated steroid by hydrogenating said peroxide in the presence of a Raney nickel or poisoned palladium catalyst, e.g. in an inert organic solvent such as an ether, dioxan, a lower alcohol or an ester-particularly ethyl acetate.  The steroid peroxides used in the above process may contain double bonds at the 6(7) and 8(9) positions, and in this instance Raney nickel saturates the 6(7) double bond as well as forming the hydroxyl groups at the 11- and 14-positions.  Poisoned palladium catalyst is the preferred catalyst when it is desired to retain all nuclear double bonds.  The catalysts have no effect on any side chain double bond.  Suitable reactants for use in the above process are isodehydroergosterol, and its esters and ethers, which yield the corresponding compounds having hydroxyl groups in the 11- and 14-positions and having a single nuclear double bond in the 8(9) position or two nuclear double bonds at the 6(7)- and 8(9)-positions.  In the examples ergosta - 6,8(9),22 - triene - 3b  - 11,14-triol - 3 - acetate and ergosta - 8(9),22 - diene-3b ,11,14-triol-3-acetate are prepared.  Specification 726,920 is referred to.
