Filed: 1935-09-12
Abstract: The process for the oxidation of pregnenol-3-ones-20 to pregnendiones with intermediate protection of the nuclear double bond by halogen according to the parent Specification is modified in that during the oxidation the nuclear double bond is protected by a hydrogen halide preferably hydrogen chloride.  As oxidizing agents there may be used as in the parent Specification compounds of hexavalent chromium such as chromium trioxide, permanganate compounds of the alkali and alkaline earth metals, and hydrogen peroxide.  After the oxidation the hydrogen halide can be removed by alkaline reacting agents such as potassium acetate or pyridine. In examples: (1) a solution of pregnenol-3-one-20 in an ether-alcohol mixture is treated with dry hydrobromic acid gas with cooling.  The hydrobromide so formed is oxidized in glacial acetic acid solution with chromium trioxide at room temperature for 2 days.  The brominated diketone is treated with potassium acetate to yield pregnendione; (2) pregnenol-3-one-20 is converted into its hydrochloride, oxidized, and the hydrogen chloride removed as described in example (1).  Specification 445,189 is referred to.  Samples have been furnished under Sect. 2 (5) of Pregnendione made as follows: (1) pregnenol-3-one-20 is converted into its hydrochloride as described in example 2, and a benzene solution of the hydrochloride oxidized for 6 hours at room temperature with an aqueous acid permanganate solution.  The product is treated with sulphur dioxide to bring the manganese dioxide into solution and the benzene layer separated and treated with alcoholic potassium acetate to form pregnendione; (2) an ether solution of pregnenol-3-one-20 is converted into its hydrochloride by treatment with alcoholic hydrochloric acid, and the hydrochloride oxidized in glacial acetic acid solution with chromium trioxide. The pregnendione hydrochloride is converted into pregnendione by boiling with pyridine for 5 hours.
