The present invention relates to a method for producing 3-keto-△ 4 -steroids, more specifically, 3-hydroxy-△ 4 or 5-steroids.
- A method for producing 3-keto- Δ4 -steroids by heating and dehydrogenating steroids under reduced pressure in the presence of a copper oxide catalyst. 3-Keto-△ 4 -Those with the structure of steroids include testosterone (male hormone),
There are important steroids such as progesterone (progesterone) and cortisone (adrenocortical hormone). Conventionally, 3-keto-△ 4 -steroids have generally been produced by the Otspenauer oxidation method of 3-hydroxy-△ 5 -steroids [for example, D.A.
Shepherd et al.: Journal of the American
Chemical Society, Vol. 77, pp. 1212-1215 (1955) or Organic Synthesis, Vol. 21,
See page 18 (1941)]. However, this method was difficult in terms of industrial operation because it required a large amount of solvent, 2 or more equivalents of hydrogen acceptor, and about 0.5 molar equivalent of aluminum alcoholate. In addition, a method of oxidizing 3-hydroxy-△ 5 -steroid with Raney-nickel-acetone [SK
Banerjee et al.: Tetrahedron, Volume 24, 6459-6467
(1968)], but this method also requires a large amount of catalyst and hydrogen acceptor, and the yield is only about 30%, so it cannot be called an industrial method. Furthermore, E. Hernholtz (E.
Fernholz) used copper oxide in an amount three times that of the raw material steroid to produce △ 5 -pregnen-3β-ol-20.
A method to obtain △ 4 -pregnene-3.20-dione by heating it at 310°C for 20 minutes [Berichte der
Deutschen Chemischen Gesellschaft, Volume 67,
No. 2027-2031 (1934)]. However, the yield of this method is extremely low at 5%, and it is not possible to implement it industrially. The present inventor was researching E. Hernholtz's dehydrogenation reaction using copper oxide, and found that water was formed and attached to the surface of the copper oxide catalyst during the dehydrogenation reaction, inhibiting the reaction and stopping it. , reaction temperature
In the range of 170-280℃, preferably 240-270℃, degree of vacuum 50-600mmHg, preferably 100-300mm
If the reaction is carried out with Hg and the water on the surface of the catalyst is removed from the reaction system, it is possible to prevent the reaction from stopping due to inhibition, and furthermore, the cause of the side reaction is that the surface of copper oxide is oxidized or basic. , PH of catalyst surface
It was discovered that side reactions could be avoided by adjusting the ratio to 7 to 8, and the present invention was completed by successfully increasing the reaction rate to 80 to 98%. Examples of the raw material 3-hydroxy- Δ4- or 5 -steroid to which the method of the present invention can be applied include those whose core is represented by the following general formula (). Gonan (A, B, R=H) Estran (A, R=H, B=CH 3 ) Androstane (A, B=CH 3 , R=H) Pregnane (A, B=CH 3 , R=C 2 H 5 ) Coran (A, B=CH 3 , R=CH (CH 3 )

Regular copper oxide fired at ~500°C can be used. The surface properties of the copper oxide catalyst produced differ depending on the type of copper salt, and this can be determined by the pH of the washing water with distilled water. However, in the present invention, it is necessary that the surface pH of the copper oxide catalyst is 7 to 8, and this is adjusted as follows. For example, the surface of copper oxide obtained by thermal decomposition of copper nitrate often shows acidity, but this can be fixed by washing thoroughly with water, and the baked products of copper hydroxide and copper carbonate can be made basic. It is difficult to bring the surface to pH 7 to 8 by washing with dilute hydrochloric acid and then water.
can be adjusted to The copper oxide whose pH has been adjusted in this way is fired again at about 200°C and used as a catalyst. The amount of catalyst used is 5 to 40% of the raw material steroid.
% by weight is preferred, especially about 20% by weight. The reaction is completed after 0.5 to 1.5 hours, usually 1 hour, at the above-mentioned reaction temperature and reduced pressure. Completion of the reaction is confirmed by observing the cessation of generation of hydrogen gas and produced water. Next, an example will be given and explained. Example 1 Aqueous ammonia was added to a copper nitrate solution to separate copper hydroxide, and the solution was heated to 180 to 200°C in air to obtain copper oxide. This washing water had a pH of 8 or higher (CuO−
). When this was washed once with 1N hydrochloric acid and then with water,
The pH was 4 or less (CuO−). By further washing with water three times, the pH of the washing water became 7.2 to 7.4 (CuO-). The following experiment was conducted using these three types of copper oxide. △ 5 g of 5-cholesten-3β-ol (commonly known as cholesterol) and 1 g of copper oxide were passed through a cooling tube without solvent, maintained at 150 mmHg, and stirred at 260°C for 1 hour.
The mixture was heated and reacted for an hour. The product was analyzed by gas chromatography, and in the case of CuO-, it was recrystallized from petroleum ether to produce △ 4 -cholesten-3-one.
4.58g was obtained. Melting point: 79-82°C [α] D +87° (ethanol). The results are shown in Table 1.
