The present invention is based on the general formula It relates to a 5-substituted uracil derivative represented by [wherein R is a hydrogen atom, a halogen atom, or an alkyl group]. The 5-substituted uracil derivative () of the present invention is a new substance and is useful as an anticancer agent and as an intermediate for the synthesis of an anticancer agent. The 5-substituted uracil derivative () of the present invention has the general formula [In the formula, R is the same as above] Compound and formula It is produced by reacting 2,5-diacetoxytetrahydrofuran shown in Compounds () and 2,5- which are the principle of the present invention
Diacetoxytetrahydrofuran () is a known compound, among which compound () can be prepared by known methods such as Acta Chemica Scandinavica by N.Elming and N.Clauson-Kaas.
Scandinavica) 6 , 535 (1952). Among the substituents R of the compound (), the alkyl group includes those having 1 to 8 carbon atoms, such as methyl, ethyl, propyl, hexyl, octyl, and the like. The reaction of the present invention can be carried out in a solvent or without a solvent. Examples of the solvent used include nonpolar solvents such as methylene chloride, ethylene chloride, benzene, and toluene, and polar solvents such as acetonitrile, nitromethane, dimethylformamide, and pyridine. The reaction proceeds without a catalyst, but in the presence of a catalyst such as a Lewis acid such as stannic chloride, antimony pentachloride, boron trifluoride ethyl ether, or an alkali metal halide such as sodium iodide, potassium bromide, lithium iodide, etc. The reaction is accelerated below. The reaction temperature is usually about -
The temperature is 30-150°C, preferably about 0-100°C. In the present invention, the ratio of the compound represented by the general formula () and 2,5-diacetoxytetrahydrofuran () to be used may be appropriately selected, but usually the latter is used in moles or more relative to the former, preferably about 1 to
It is better to use 3 times the mole. The amount of the catalyst used is not particularly limited, but it is preferably used in a molar ratio of about 0.001 to 2 with respect to the compound represented by the general formula (). The compound of the present invention can be purified by conventional methods such as recrystallization and column chromatography. Examples are given below to explain the present invention in detail. Example 1 27.5 g of 2,4-bis(trimethylsilyl)-5-fluorouracil and 22.6 g of 2,5-diacetoxytetrahydrofuran were mixed with methylene chloride.
Dissolve in 200ml. Add 0.23 ml of stannic chloride and stir at room temperature for 4 hours to react. 200 ml of methylene chloride was added to the reaction solution, and this solution was washed with 200 ml of an aqueous sodium hydrogen carbonate solution and then with 20 ml of water. After concentrating the methylene chloride solution, the residue was recrystallized from benzene-acetone (1:1) to give 1- (5′−
