It can be synthesized by subjecting a Schiff base (azomethine derivative) obtained by reacting a pseudo amino sugar such as validamine or valienamine with a cycloalkanone such as cyclohexanone or cyclopentanone to a reduction reaction. The condensation reaction between the amino group of the pseudo-amino sugar [] and the cycloalkanone and the subsequent reduction reaction may be carried out continuously in the same reaction vessel, or both reactions may be carried out separately in two stages. You may do so. Examples of reaction solvents include water, alcohols such as methanol, propanol, and butanol, glymes such as dimethyl sulfoxide, dimethylformamide, N-methylacetamide, methyl cellosolve, dimethyl cellosolve, and diethylene glycol dimethyl ether, dioxane, tetrahydrofuran, and acetonitrile. A polar solvent, a mixed solvent thereof, or a mixture of these polar solvents and a nonpolar solvent such as chloroform or dichloromethane can be used. The reaction temperature in the Schiff base formation reaction is not particularly limited, but it is usually carried out at room temperature to about 100°C. The reaction time varies depending on the reaction temperature and the type of aldehyde or ketone used, but it is usually several minutes to 24 minutes.
The purpose can be achieved by allowing the reaction to take some time. Various metal hydride complex reducing agents such as sodium borohydride, potassium borohydride, lithium borohydride, sodium trimethoxyborohydride, etc. can be used for the reduction reaction of the Schiff base formed. , alkali metal cyanoborohydride such as sodium cyanoborohydride, alkali metal aluminum hydride such as lithium aluminum hydride, and dialkylamine borane such as dimethylamineborane are advantageously used. In addition, when using an alkali metal cyanoborohydride, for example, sodium cyanoborohydride, it is preferable to carry out the reaction under acidic conditions, for example, in the presence of hydrochloric acid, acetic acid, or the like. The reaction temperature is not particularly limited, but it is a normal temperature,
In some cases, especially in the early stages of the reaction, the reaction is carried out under ice-cooling, or in some cases heated to about 100° C., and the reaction varies depending on the Schiff base to be reduced and the type of reducing agent. The reaction time also varies depending on the reaction temperature and the type of Schiff base and reducing agent to be reduced, but the purpose can usually be achieved by allowing the reaction to occur for about several minutes to 24 hours. In the reduction reaction of the formed Schiff base, catalytic reduction can also be used when the pseudo-amino sugar used as a raw material does not have an unsaturated double bond like variolamine and validamine. That is, the reaction is carried out by shaking or stirring Schiff's base in a suitable solvent in the presence of a catalyst for catalytic reduction in a hydrogen stream. Catalytic reduction catalysts used include, for example, platinum black, platinum dioxide, palladium black, palladium carbon, Raney nickel, etc., and commonly used solvents include, for example, water, alcohols such as methanol and ethanol, dioxane, tetrahydrofuran, Dimethylformamide or a mixed solvent thereof is used. The reaction is usually carried out at room temperature and normal pressure, but may also be carried out under pressure or with heating. The N-substituted derivatives of pseudo-amino sugars included in the present invention can also be synthesized by the following method. That is, pseudo-amino sugars such as variolamine, validamine, and valienamine are mixed with bromocyclohexane, chlorocyclohexane, bromocyclopentane, chlorocyclopentane, 2-bromocyclohexanol, 2-chlorocyclohexanol, 2- It can be synthesized by reacting with a cycloalkane halide such as bromocyclopentanol or 2-chlorocyclopentanol. Suitable reaction solvents include, for example, water, lower alkanols such as methanol, ethanol, propanol and butanol, ketones such as acetone, methyl ethyl ketone and methyl isobutyl ketone, dimethyl sulfoxide, dimethyl formamide, N
- Glymes such as methyl acetamide, methyl cellosolve, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, polar solvents such as dioxane, tetrahydrofuran, acetonitrile, or mixed solvents thereof, or non-polar solvents such as benzene, hexane, chloroform, dichloromethane, ethyl acetate, etc. A mixed solvent with a solvent is used, and if the mixed solvent is not a homogeneous phase, the reaction may be carried out in the presence of a phase transfer catalyst. In this reaction, examples of deoxidizing agents include alkali metal hydrogen carbonate, alkali metal carbonate, alkali metal hydroxide, trimethylamine, triethylamine, tributylamine, N-methylmorpholine, N-methylpiperidine, N,N-dimethylaniline, pyridine, Inorganic and organic bases such as pyricholine, lutidine, etc. can also be used. Although the reaction temperature is not particularly limited, it is usually carried out by heating from room temperature to about 100°C. The reaction time varies depending on the reaction temperature, but is usually within a few minutes.
The purpose can be achieved by reacting for about 24 hours. The content of the present invention will be explained in detail by referring to Reference Examples and Examples below, but the scope of the invention is not limited thereto.
