Definitions
- the present invention relates to a production method for obtaining substituted or unsubstituted adamantyl (mono or poly) acetic acid and substituted or unsubstituted adamantyl (mono or poly) ethanol in high yield and high purity.
- Adamantane has a structure in which four cyclohexane rings are condensed into a cage shape, is a highly symmetrical compound with high symmetry, and its derivative exhibits a unique function. It is known to be useful as a raw material for highly functional industrial materials. For example, since it has optical characteristics, heat resistance, etc., it has been tried to apply it to an optical disk substrate, an optical fiber, or a lens (for example, see Patent Document 1 and Patent Document 2).
- a pharmaceutical having a structure derived from substituted or unsubstituted adamantylethanol among these derivatives can be a TNF- ⁇ production inhibitor useful as a therapeutic agent for autoimmune diseases.
- the importance of substituted or unsubstituted adamantylethanol is increasing (see, for example, Patent Document 4).
- 1-adamantylacetic acid or 1-adamantylacetoaldehyde is once synthesized and then synthesized. There are known methods for reducing
- acetylene is a high-pressure gas with high danger, and special equipment is required for use, and it is difficult to say that it is a general industrial production method.
- a further problem with the prior art is the generation of impurities in the manufacturing process. Since all of the above methods use highly reactive reagents such as boron trifluoride and acetylene, adamantyl diacetic acid (disubstituted acetic acid) is used as an impurity in addition to the target adamantyl acetic acid (monosubstituted acetic acid). Body) is a by-product. For this reason, when the obtained adamantyl acetic acid is directly reduced to an alcohol form, a diethanol form is produced.

- Example 10 the reaction was performed in the same manner as in Example 10 except that 2 g (8 mmol) of 1,3-adamantyldiacetic acid was used instead of 1-adamantylacetic acid. As a result, 1, 3 - was obtained ⁇ Damman Tan diethanol at a yield 91.2 mass 0/0, GC purity 99.4%.
- adamantane compounds and vinylidene halides are raw materials for drugs that inhibit TNF- ⁇ production that are useful as a raw material for agricultural chemicals and pharmaceuticals, especially as a therapeutic agent for autoimmune diseases, by applying specific processes.
- Substituted or unsubstituted adamantyl (mono or poly) ethanol can be produced efficiently.
