The present invention describes a novel semi-synthetic aminoglycoside antibiotic, 3'-fluoro-3'-deoxykanamycin B.
and its manufacturing method. This new compound exhibits high antibacterial activity against various kanamycin-susceptible and kanamycin-resistant bacteria and is useful as an antibacterial agent. Various deoxy derivatives of kanamycin A, B, and C are known as semisynthetic aminoglycoside antibiotics derived from kanamycin A, B, and C. Although these previously known deoxykanamycin derivatives have useful antibacterial activity, their antibacterial spectrum varies widely and new resistant bacteria may emerge and render them ineffective, so new and better antibacterial agents are needed. There is a constant desire to create chemical compounds. The present inventor has discovered that kanamycin A
If we can create a derivative in which the hydroxyl group at the 3' position is replaced with a fluoro group, that is, 3'-fluoro-3'-deoxykanamycin A, we expect that this will be a compound that is effective against kanamycin-resistant bacteria. succeeded in synthesizing. That is, the present inventors disclosed in the previous Japanese Patent Application No. 161615/1989 (see Japanese Patent Application Laid-open No. 40297/1989) that 3'-fluoro-3'-deoxy as a novel semi-synthetic aminoglycoside antibiotic.

It was possible to produce N,O-protected 3'-iodinated, 3'-brominated or 3'-chloro derivatives of kanamycin B by the action of alkali metal iodides, bromides or chlorides ( (See Japanese Patent Publication No. 57-876, Example 1, and U.S. Pat.

Furthermore, it has been well recognized that alkali metal fluorides as nucleophilic reagents differ significantly from other alkali metal halides in terms of reaction behavior.

It has been found that methoxy (or ethoxy or benzyloxy) carbonyl-1,3,3''-tri-N-tosylkanamycin B [referred to as compound (d)] can be produced. When reacting alkali hydroxides, etc., in anhydrous methanol, anhydrous ethanol, or anhydrous benzyl alcohol, by increasing the reaction temperature, reaction time, working concentration, etc. at which the alkali metal hydroxide acts, etc. When the reaction conditions are made more severe than the appropriate conditions mentioned above, the elimination of the 2â³-O-acetyl group and the 2â²,
Closing of the 3'-atiridine ring occurs, but at the same time, the 4',6'-cyclic carbamate moiety (O=C) from compound (c) decomposes, and the 6'-amino group It becomes unprotected and reacts undesirably with the 3'-O-sulfonyloxy group, adversely affecting subsequent reactions. Furthermore, as a result of repeated experiments and research, the present inventors found that compound (d) was obtained by converting compound (d) into sodium hydrogen difluoride or sodium hydrogen difluoride using a polar organic solvent such as anhydrous dimethylformamide or dimethylacetamide as a reaction medium. When reacted with potassium hydrogen difluoride under heating, for example, at a temperature of 120 to 200°C for a reaction time of, for example, about 10 minutes to about 20 hours, the 2',3'-aziridine ring opens and the 3'-position is fluorinated, therefore

It has been discovered that 3,3''-tetra-N-tosylkanamycin B [referred to as compound (c)] is produced.In this way, along with the opening of the aziridine ring, kanamycin is produced by the alkali metal hydrogen difluoride. As far as the inventors are aware, this is the first finding of an aminoglycoside antibiotic that the 3'-position of Compound B is fluorinated. 1
When treated with a known deprotection method that removes the amino protecting groups at -, 2'-, 3- and 3''-amino groups, the desired 3'-fluoro-3'-deoxykanamycin B (compound) was produced. .On the other hand, compound (d)
It is recognized that the 3'-fluoro-3'-deoxykanamycin B compound cannot be produced if all of the tosyl groups are first eliminated and then reacted with an alkali metal hydrogen difluoride under the conditions described above. Ta. In this way, the inventor has discovered that kanamycin B
We succeeded in developing a route to synthesize 3'-fluoro-3'-deoxykanamycin B starting from 3'-fluoro-3'-deoxykanamycin B. Furthermore, an amino protecting group (methoxycarbonyl group, ethoxycarbonyl group, or benzyloxycarbonyl group) on the 6â²-amino group of compound (d), and a hydroxyl protecting group (cyclohexyloxycarbonyl group) on the 4â³- and 6â³-hydroxyl groups dene group) is removed from compound (d), and the thus obtained 3'-deoxy-3'-epi-2',3'-(N-tosyl)epimino-1,3,
Free 3'-tri-N-tosylkanamycin B
Another type of amino protecting group such as an alkanoyl group (but not of the sulfonyl group type) is introduced into the 6'-amino group, and the N-protected -3'-
The desired N-protected -3'-fluoro-3'- It was confirmed that deoxykanamycin B compound can be produced. Starting intermediate compounds used in the synthetic route described above
In (a), the amino protecting group protecting the 1-, 2â²-, 3- and 3â³-amino groups is a tosyl group and the hydroxyl protecting group protecting the 4â³- and 6â³-hydroxyl groups is a cyclohexyl group. The tosyl group for amino protection was replaced with other known amino protecting groups of the sulfonyl group type that work equally well, and the 4â³- and
An equivalent protected derivative of compound (a), which can be obtained by replacing the cyclohexylidene group at the 6â³-position with other known hydroxyl protecting groups, can also be obtained by performing the same reaction steps as described above. 4â³,6â³-di-O-protected-1,3,3â³-tri-N equivalent to compound (d)
-Sulfonylation protection-3'-deoxy-3'-epi-
It has been found that 6'-N-methoxy (or ethoxy or benzyloxy) carbonyl-2',3'-(N-sulfonylation protected) epimino-kanamycin B can be prepared. The present invention was completed based on the above-mentioned findings. Therefore, the gist of the second invention is as follows:

åŒA method for producing 3'-fluoro-3'-deoxykanamycin B represented by: In the method of the second invention, the general formula ()
Amino protecting group A in 3'-deoxy-3'-epi-2',3'-epimino-kanamycin B protected derivative
is any known amino protecting group that does not participate in the reaction,
For example, alkanoyl groups such as acetyl group, trifluoroacetyl group, acyl groups such as aroyl group such as benzoyl group, and alkoxycarbonyl groups such as methoxycarbonyl group, ethoxycarbonyl group, butoxycarbonyl group; benzyloxycarbonyl group, phenethyl group. It can be an aralkyloxycarbonyl group such as an oxycarbonyl group, or an aryloxycarbonyl group such as a phenoxycarbonyl group or a methoxyphenoxycarbonyl group. However, if the group A is a sulfonyl group type such as an alkylsulfonyl group such as a mesyl group or a tosyl group, an arylsulfonyl group, or an aralkylsulfonyl group, undesirable by-products will be produced during the reaction of the alkali metal hydrogen difluoride. The amino protecting group (A) is not of the sulfonyl group type due to concerns. Although the group (A) can be a hydrogen atom, it is preferable that the 6'-amino group of the compound () is protected. 1-, 3- and in the compound of general formula ()
The 3''-amino group is protected with an amino protecting group (B) of the type of an alkylsulfonyl group such as a mesyl group or a trifluoromethylsulfonyl group, an aralkylsulfonyl group such as a benzylsulfonyl group; an arylsulfonyl group such as a tosyl group. The sulfonyl group Q bonded to the nitrogen atom of the 2â²,3â²-atiridine ring is preferably the same sulfonyl group as B. The 4â³-hydroxyl group and
Protecting group (X, Y) that protects the 6â³-hydroxyl group
can be any known monovalent hydroxyl protecting group, including lower alkyl groups, aryl groups such as phenyl groups; alkanoyl groups such as acetyl groups, or aroyl groups such as benzoyl groups.
However, X and Y may jointly be any known divalent group, including a lower alkylidene group such as an isopropylidene group, an aralkylidene group such as a benzylidene group, a cycloalkylidene group such as a cyclohexylidene group, or a tetrahydropyranylidene group. It may form a hydroxyl protecting group. Introduction of these amino-protecting groups and hydroxyl-protecting groups into kanamycin B compounds has been described, for example, in JP-A No. 55
â105699, British Patent No. 2043634B; Japanese Patent Application Publication No. 1983
â68698, U.S. Patent No. 4357466; Japanese Patent Application Publication No. 1983-
This can be accomplished using conventional protection techniques such as those described in US Pat. No. 152,497 and US Pat. No. 4,359,572. In the second method of the present invention, the alkali metal hydrogen difluoride () to be reacted with the N,O-protected 2',3'-epiminated kanamycin B compound of the general formula () is NaHF 2 , KHF 2 or LiHF2 , but KHF2 is preferred. This reaction may be carried out in a dry organic solvent suitable for the reaction, but is preferably carried out in a polar organic solvent such as dimethylformamide, dimethylacetamide, acetonitrile or sulfolane. Dimethylformamide is most suitable. Depending on the type of organic solvent used, the desired reaction may not proceed. The reaction is carried out under heating, and the reaction temperature is suitably in the range of 120 to 200°C. Preferably, the temperature is within the range of 150 to 160°C. The above reaction produces a 3'-fluoro-3'-deoxy-kanamycin B protected derivative of the general formula (), which can be collected by extracting the reaction solution with a suitable organic solvent such as ethyl acetate, and then extracting it with silica gel. This can be carried out by separation and purification using column chromatography. If an amino protecting group and/or a hydroxyl protecting group remain in the compound of general formula (),
The protecting group is removed in the deprotection step. This deprotection step is carried out in stages depending on the type of protecting group used, using a commonly used deprotection method and a known method, such as the method disclosed in the above-mentioned Japanese Patent Application Laid-Open No. It can be done. The reaction solution obtained in this deprotection reaction is concentrated, and the solid residue is dissolved in water, passed through a CM-Sephadex C-25 column, and developed with aqueous ammonia to isolate and purify the desired product. 3'-fluoro-3'-deoxykanamycin B [compound ()] can be obtained. The gist of the third invention is the following general formula
