Definitions
- the present invention relates to an optically active 2-2-troimidazole derivative, a method for producing the same, and an intermediate for producing the same.
- the present invention relates to an optically active 2-2-troimidazole derivative useful as a drug to be used in combination for radiotherapy of tumor, a radiosensitizer containing the same as an active ingredient, a method for producing the derivative, and an intermediate for producing the derivative.
- the 2-nitroimidazole derivative represented by the formula (1) has the effect of increasing the radiosensitivity of hypoxic cells in the tumor, that is, has an excellent radiosensitizing effect and is highly safe. It is known that it is useful as a concomitant drug for radiation therapy (Japanese Patent Application Laid-Open No. 3-223258).
- This method selectively silylates a total of three hydroxyl groups, two primary hydroxyl groups and one secondary hydroxyl group, out of the four glacial groups of erythritol, which is the starting compound. It is a process that requires a low-temperature reaction to create a difference in the reactivity between primary and secondary hydroxyl groups.However, a large amount of solvent is required because the solubility of the starting compounds is low. .
- the product obtained in this step is obtained as a mixture of tetra-silylated, tri-silylated, di-silylated, mono-silylated and unreacted products, and only the desired tri-silylated product is selectively obtained.
- the above 2--2-throimidazole derivative (5) has two asymmetric carbon atoms, and it is difficult to separate the optically active form. No successful examples have been reported. No pharmacological action of the optically active substance is known at all.
- an object of the present invention is to provide an optically active form of a 2-2-throimidazole derivative (5) and a medicament containing the same as an active ingredient.
- Another object of the present invention is to provide a novel method for producing a 2-nitroimidazole derivative (5) and an intermediate for producing the same.
- the inventors of the present invention have conducted intensive studies in view of the above circumstances, and have found that 2-halomethoxy-1,3,4-trimethylsiloxybutane obtained by ring-opening a dioxolane compound using an inexpensive tartaric acid diester as an intermediate. It has been found that by passing through, it is possible to industrially and advantageously obtain a 2-2 troimidazole derivative and an optically active substance thereof in a low yield. The present invention has been completed.
- the present invention provides the following equations (1) to (4)
- the present invention relates to an optically active 2- (2- ⁇ ) -imidazole derivative represented by any one of the above and a radiosensitizer containing the same as an active ingredient.
- the present invention further provides the following reaction formula Lewis acid
- RR 2 and R 3 are the same or different and represent an aliphatic group or an aromatic group, and X represents a halogen atom
- the present invention relates to a method for producing a 2-2-to-imidazole derivative represented by the formula and an intermediate for the production thereof.
- the present invention is characterized in that a 1,3-dioxolane derivative (9), which can be easily produced from a tartaric acid diester (6), is reacted with a silhalide (10) to form a 2-halomethoxy-1,3,3. 4-
- a siloxybutane derivative (11) is reacted with a silhalide (10) to form a 2-halomethoxy-1,3,3.
- the present invention provides a method for producing a 2-nitro- ⁇ -imidazole derivative (1 2), which comprises reacting the 2-halomethoxy-1,3,4-triacyroxybutane derivative (1 1) with 2-2 troimidazole. It relates to the manufacturing method.
- the present invention is characterized by reacting 2-halomethoxy-1,3,4-triacyroxybutane derivative (11) with 2-ditroimidazole and leaving the obtained compound (1 2) for silylization.
- the present invention relates to a method for producing a 2-2 troimidazole derivative (5).
- examples of the aliphatic group represented by RR 2 and R 3 include a linear, branched or cyclic alkyl or alkenyl group having 1 to 24 carbon atoms. Specific examples thereof include a methyl group, an ethyl group, an n-propyl group, an isopropyl group, a dibutyl group, an isobutyl group, an n-octyl group, a palmityl group and the like.
- examples of the aromatic group include a phenyl group and a naphthyl group.
- examples of the IDgen atom represented by X include a fluorine atom, a chlorine atom, a bromine atom and an iodine atom.
- the reaction for obtaining compound (7) from compound (6) is preferably carried out by adding phosphorus pentoxide little by little to a mixture of compound (6) and dimethoxymethane at room temperature or under heating. .
- the reaction for obtaining the compound (8) from the compound (7) is a reaction in which the compound (7) is reacted with a Lewis acid to close the ring.
- the Lewis acid to be reacted with compound (7) include boron trifluoride, boron trifluoride etherate, anhydrous zinc chloride, anhydrous aluminum chloride, anhydrous tin chloride and the like.
- the reaction between the compound (7) and the Lewis acid may be performed by adding an equivalent amount of a Lewis acid from the catalytic amount to the compound (7) and stirring the mixture at room temperature or under heating.
- a partial ring closure reaction occurs due to the action of phosphorus pentoxide, and proceeds until a 1,3-dioxolane derivative (8) is formed.
- the ring closure reaction can be completed by adding a Lewis acid as it is without performing the reaction.
- the reaction for obtaining the compound (9) from the compound (8) can be carried out by reducing the compound (8) and then reacting an aliphatic or aromatic carboxylic acid or a reactive derivative thereof.
- a reducing agent such as lithium aluminum hydride and sodium borohydride.
- examples of the reactive derivative of an aliphatic carboxylic acid or an aromatic carboxylic acid include an acid halide and an acid anhydride.
- the acylation reaction is preferably carried out according to a conventional method, for example, in the presence of a base such as pyridine, from room temperature to heating.
