Description: PROPYLAMINE DERIVATIVE AND PROCESS OF MANUFACTURING THE SAME Background of the invention (1) Field of the invention The present invention relates to a propylamine derivative and a process of manufacturing the same. The propylamine derivative obtained by the present invention may readily lead to amino acids having functional groups such as glutamine, proline, ornithine, glutamic acid, etc. by further effecting hydrolysis, hydrogenation, and the like. (2) Description of the prior art. Conventionally, there have been known various processes for producing a-amino acids, of which, for example, the following methods (1) to (3) have recently been proposed as improved processes for effecting reactions under mild conditions. EMI2.1 R = alkyl group aralkyl group X = I, Br [Tetrahedron Lett. 2641 (l978) EMI2.2 R = alkyl group, aralkyl group X = Cl, Br, CH3OSO3 Tetrahedron Lett. 4625 (1978] EMI2.3 E (electrophile); cinnamyl bromide dimethyl p-chlorobenzalmalonate nitrostyrene Org. Chem. 42 2640 (1977)0 Howeyer, the known methods as described above still have some problems to be solved with respect to the points as follows. (a) In those methods, the Schiff bases are produced under mild conditions at ordinary temperature and atmospheric pressure, but the required reaction times are rather long. (b) In each case of the above methods (1), (2), and (3), an sincevalkylhalide is employed as the material for producing said Schiff bases, it is necessary to further add a functional group on the alkyl radical of the Schiff bases, to get an intermediate for producing an amino acid having three functional groups, for example, glutamine, proline ornithine, and glutamic acid. However, owing to the fact that the Schiff bases are very sensitive to the chemical reaction, it is difficult to effect a specific reaction for introduction of a new functional group, and thus, normally, several kinds of products are undesirably obtained simultaneously. (c) In method (3), amidine represented by EMI3.1 and employed as a starting material is an expensive reagent in itself, is difficult to synthesize, and therefore is unsuitable to be used as a starting material industrially (d) The yields of 70 to 80% are rather low and are considered to be insufficient for an industrial production. Therefore, it has been strongly desired to provide a process of synthesizing an amino acid intermediate which is more economical with a higher yield and a better suitability for general purposes than the conventional techniques as described above. Object of the invetion Accordingly, a primary object of the present invention is to provide intermediates which are into chemically stable and can be converted several amino acids having functional groups. A secondary object of the present invention is to provide processes of manufacturing the intermediates as described above with the employment of a material readily available, under mild conditions ih good yields. A third object of the present invention is to provide processes of manufacturing the intermediates for the production of amino acids wherein benzophenone recovered as a by-product during manufacture of amino acids from the above intermediates'is recycled. Brief description of the invention These and other objects of the present invention will be accomplished by obtaining propylamine derivatives represented by the general formula (I), EMI5.1 wherein R1 and R2 are identical or different radicals selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, cyano, and carbamoyl, or RÚ and Rê form in combination a cyclic imide, and O is a phenyl radical. Here, the above derivativeof the formula (I), EMI5.2 (wherein RÚ is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, and 2 cyano vcarbamoyl, and R2 is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, and butoxycarbonyl Vcyano, or R1 and R2 form in combination a cyclic imide, and f is a phenyl radical), can be obtained by subjecting olefins represented by the general formula (tri), R1 ¯ CH = CH2 (11) (wherein Rl is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, cyano, and carbamoyl); and Schiff bases represented by the general formula (III), EMI6.1 (wherein.Rê is a radical selected from the group consisting methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, and cyano, and f is a phenyl radical), to reaction at a reaction temperature of from -80 OC to 80 OC, with or without use of a catalyst in the presence of bases in a monophase or two-phase solvent system. Alternatively, the above derivatives of the formula (I), EMI6.2 (wherein R1 and R2 are identical or different radicals selected from the group consisting of cyano, and carbamoyl, with at least one of the radicals for R and R2 being carbamoyl, and ° is a pheny radical), can be obtained by subjecting the compound of the following general formula (I), EMI7.1 (wherein R1 is a radical selected from the group consisting methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, cyano, carbamoyl, and Rê is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, and 1 2 propoxycarbonyl, butoxycarbonylv cyano, or Rl and R form in combination a cyclic imide, and ° is a phenyl radical), to reaction with ammonia at a temperature of from -200C to 800C under atmospheric pressure or under increased or reduced pressure in the presence of a solvent. Detailed description of the invention Hereinbelow, the processes of the present invention will be first described and, then, the novel compounds prepared by the process will be described. In the first, olefins for the starting material represented by the formula (II) are prepared. R1 - CH = CH2 (11) wherein R1 is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, cyano, and carbamoyl Olefines as described above are methylacrylate, ethylacrylatet propylacrylate, butylacrylate acrylonitrile or acrylamide. Meanwhile, Schiff bases represented by the general formula (III) are prepared as the other starting material. EMI8.1 wherein R2 is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, . butoxycarbonyl, and cyano, - and 0 is a phenyl radical. The Schiff bases of formula (III) usable for the present invention may be prepared by two processes. One is a process wherein a glycine ester obtained by reacting glycine with an alcohol of 1 to 4 carbon atoms is subjected to a dehydration reaction with benzophenone [Tetrahedron Lett., No.30, 2641 (1978)g. The other is a process wherein .g.lycinonitrile is reacted with benzophenone [Tetrahedron Lett., No.30, 4625 (1978)0. N-(diphenylmethylene) glycine alkyl esters are obtained by the former process and N (diphenylmethylene)glycinonitrile is obtained by the latter process. As the N-(diphenylmethylene) glycine alkyl esters, there may be mentioned methyl N- (diphenylmethylene) glycinate, ethyl N- (diphenyl- methylene) glycinate1 propyl N- (diphenylmethylene) ylycinate and butyl N- (diphenylmethylene) glyciilatev Olefines and Schiff bases thus obtained are reacted together. The reaction may be effected by two processes. One is a process wherein the reaction is effected in a homogeneous solvent, i.e. a monophase solvent system, the other is a process wherein the reaction is effected in a two-phase solvent system consisting of an aqueous phase and an organic phase. The reaction is carried out in the solvent, in the presence of a base, with or without the use of a catalyst, and at a temperature of from -800C to 800C. Although the catalyst is not required for the reaction in the monophase solvent system it is preferable to employ a catalyst for effecting the reaction by the two phase solvent system. As the catalyst, there may be employed halides, hydrogensulfates or hydroxides of tetraalkylammoniums or benzyltrialkylammoniums, having 1 to 16 carbon atoms in each alkyl group, preferably quaternary ammonium salts such as tetrabutylammonium hydrogensulfate, benzyltrimethylammonium chloride, benzyltrimethylammonium hydroxide, cetyltrimethylammonium bromide, dodecyltrimethylammonium chloride and tetraethylammonium hydroxide, more preferably tetrabutylammonium hydrogensulfate, benzyltrimel ammonium hydroxide and tetraethylammonium hydroxide. The catalyst may be employed in an amount of from 0.0001 to 1 equivalent, preferably 0.001 to 1 equivalent, based on the Schiff base. If the catalyst is employed in an amount less than 0.0001 equivalent, both the yield of the final product and the reaction rate are low. If the amount of the catalyst is larger than 1 equivalent, it is difficult to isolate the final product from the reaction mixture. The reaction temperature should be from -800C to 800C, preferably -800C to 400C. Where the temperature is too low, the reaction proceeds too slowly. When the temperature is too high, side reactions may undesirably occur and, further, in the case of the reaction in the two-phase solvent system, hydrolysis may undesirably occur. The base may be employed in an amount of from 0.001 to 10 equivalents, preferably 0.001 to 5 equivalents, based on the Schiff base. In the case of the reaction in the monophase solvent system, there may be employed, as the solvent, aliphatic alcohols such as methanol, ethanol, propanol and butanol, halogenated hydrocarbons such as dichloromethane, chloroform, trichloroethylene and trichloroethane, aromatic hydrocarbons such as benzene, toluene and xylene, ethers such as diethyl ether, tetrahydrofuran and dioxane, dimethylformamide, and dimethyl sulfoxide. When these solvents are employed in the reaction system, it is preferable to employ a base selected from alkali metal hydrides, hydroxides, amides and alcoholates. In the case of the reaction in the two-phase solvent system, there may be employed a mixture of water with at least one organic solvent selected from the above-mentioned halogenated hydrocarbons, ethers, aromatic hydrocarbons, dimethylformamide and dimethyl sulfoxide. In such a case, there may preferably be employed, as the base, hydroxides, carbonates and hydrogencarbonates of alkali metals such as sodiumhydroxide, sodium carbonate and sodium hydrogencarbonate.. However, where an alkali metal hydroxide is used, chloroform and trichloroethylene should not be employed in the solvent since explosive compounds, such as carbene and dichloroacetylene, may probably be formed in the system. In both the above-mentioned reactions, the starting materials may be employed in an approximately stoichiometric amount, preferably 0.8 to 1.2 mol equivalent of the oleo in should be employed based on the Schiff base. The reaction may be carried out under atmospheric pressure or under increased or reduced pressure, preferably under atmospheric pressure. The reaction may be effected batch-wise, continuously or semicontinuously. In the case of the batch-wise reaction, the reaction may usually be completed in from 5 to 120 minutes. Where the reaction is effected batch-wise, it is preferably that the oleo in is added to a mixture of the Schiff base, the base, the solvent and the catalyst (if any) with stirring. After the completion of the reaction, upon separation of the product by the known method, propylamine derivatives represented by the following formula (I) are obtained. EMI12.1 (wherein R1 is a radical selected from the group consisting of methoxycarbonyl, ¯ ethoxycarbonyl, propoxycarbonl, butoxycarbonyl, cyano and carbamoyl, and R2 is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, cyano, or R1 and R2 form in combination a cyclic imide, and ° is a phenyl radical) After the completion of the reaction, the product of formula I, as hereinbefore defined, may the be isolated in v usual way. For example, where the two-phase solvent system is employed, the solvent is removed from the organic phase which is separated from the aqueous phase after the completion of the reaction, and the residue is passed through a column packed with silica gel. As the developing solvent, cyclohexane or a mixture of cyclohexane and ethyl acetate may suitable be used. After the removal of the solvent from the eluate !under reduced pressure, pure propylamine derivatives are obtained. In the case where the desired compound is isolated from the reaction mixture obtained in the monophase solvent system, since there exists in the reaction mixture a compound which should not be brought into contact with water, such as sodium, potassium or sodium alcoholate, such a compound should first be decomposed carefully with a little water. The organic phase is concentrated, and then the product is isolated as mentioned above in a similar manner as in the two-phase solvent system The propylamine derivative (referred to as a cyclic imide propylamine derivative) represented by the following general formula (I), EMI14.1 (wherein R1 and R2 form in combination a cyclic imide) is obtained by & clization reaction of a propylamine derivative (referred to as an amideester propylamine derivative) which is represented by the following formula (I), EMI14.2 (I) as those in formulas (II) and (III) below), by reaction of olefins represented by the following formula (II), R1CH = CH2 (11) (wherein Rl is a carbamoyl group) ,with Schiff bases represented by the following formula (III), EMI14.3 (wherein Rê is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, and butoxycarbonyl, and j is a phenyl radical). The cyclization reaction as described above is very fast, but under basic conditions the cyclic imide propylamine derivative thus formed is hydrolyzed and ring opening products are obtained. In the production of the cyclic imide propylamine derivative as described above it is desirable to effect the reaction in the monophase solvent system of organic solvent substantially containing no water in order to prevent the ring opening reaction. Meanwhile, in order to obtain the amidoester propylamine derivative at a high yields it is preferable to adopt mild conditions employing, for example, a weak base such as sodium carbonate or the like. Subsequently, the propylamine derivatives obtained by the reaction between olefins and Schiff bases and represented by the general formula (I), EMI16.1 (wherein R1is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, and propoxycarbonyl, butoxycarbonyl, cyano Vcarbamoyl, and R2 is a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl Ccyano, or R1 and R2 form in combination 1 2 a cyclic imide, with at least one of Rl and R2 being a radical selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, and RÚ and Rê form in combination a cyclic imide and ° is a phenyl radical), are subjected to reaction with ammonia. The ammonia to be employed in the reaction may be in any forms such as gas, liquid, or a solution, and the like. The amount of ammonia to be employed for the reaction may be rather excessive with respect to the starting material, but in the mormally such amount is 1 to 10 equivalents based on the starting material. In the case where the ammonia is employed in a form of gas, the ammonia gas may contain any other gases which will not obstruct the reaction. If the ammonia is used in the form of a solution, 5 to 28 wt % aqueous solutions are favorably employed. The reaction temperature should be in the range of from -20 OC to 80 OC, and more preferably, from 0 OC to 40 OC. If the temperature is excessively low, the reaction proceeds too slowly, whole on the contrary, if it is too high, undesirable side reactions may take place. Although the reaction may be effected under atmospheric pressures or under increased or reduced pressure, it should preferably be effected under atmospheric pressure. For the solvents, there may be employed water; aliphatic alcohols such as methanol, ethanol, propanol, A butanol, etc.; halogenated hydrocarbons such as dichloromethane, chloroform, trichloroethylene, etc.; aromatic hydrocarbons such as benzene, toluene, xylene, etc.; ethers such as diethyl ether, tetrahydrofuran, dioxane, etc.; and dimethylformamide, and dimethyl sulfoxide. The amount of the solvent to be used may be set as desired, but normally, be 2 to 20 times the weight of the starting material. The reaction can normally be effected without employment cf any catalysts. Meanwhile, the reaction may be carried out by the batch-wise, continuously or semicontinuously In the case where the reaction is effected by the batch-wise it should normally be completed in from 0.5 to 5 hours. Moreover, in the case of the batch-wise reaction . it is preferable to gradually add ammonia into the starting material reaction mixture under stirring. After the completion of the reaction, upon separation of the resulting product, for example, by the known method as described earlier, the propylamine derivatives as represented by the following general formula (I)are obtained. EMI18.1 (wherein R1 and R2 are identical or different radicals selected from the group consisting of cyano, and carbamoyl, with at least one of RÚ and Rê being carbamoyl, and j is a phenyl radical. The crude product thus obtained is refined by the method as described earlier. Alternatively, the cyclic imide propylamine derivative may be obtained by subjecting the propylamine derivatives (referred to as an ester ester propylamine derivatives hereinbelow) represented by the following formula (I), EMI19.1 (wherein R1 and R2 are identical or different radicals selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, and butoxycarbonyl, and 0 is a phenyl radical), to reaction with ammonia in the similar manner as described earlier. More specifically, in the case where the ester ester propylamine derivatives are reacted with ammoina, the propylamine derivative represented by the following formula (I) EMI19.2 (wherein R1 and R2 are carbamoyl radical). is obtained, after passing through the cyclic imide propylamine derivative as described earlier. For manufacturing the cyclic imide propylamine derivative with a favorable yield, it is preferable the to preventVdiester from being directly formed into diamide by controlling the mole ratio of ammonia employed in the reaction to the range of from 0.8 to 1.1, and simultaneously to effect the reaction in an organic solvent not containing water so that the cyclic imide propylamine derivative thus formed is not subjected to the ring opening reaction by hydrolysis, and further, to carry out the reaction at as low a temperature as possible. In connection with the above, the forms of ammonia to be employed in the reaction, reacting temperatures, reacting pressures, kinds of solvents, amounts thereof, reaction systems, reaction times, isolating methods, refining methods, etc. may be the same as in the case of the reaction between the propylamine derivative and ammonia described earlier. According to the processes of the present invention as explained above, the following specific effects can be attained: (1) - Desired products can be obtained in a high yield. (2) - These processes can generally be carried out under a mild condition and, thus, are industrially advantageous. (3) - These processes can be carried out by a simple apparatus and operation. (4) - The Schiff bases to be used as a starting material in the present process are stable in an aqueous alkali solution and can be purified by distillation or recrystallization. The compounds according to the present invention as described in the foregoing are novel propylamine derivatives represented by the following formula (I), EMI21.1 (wherein RÚ and Rê are identical or different radicals selected from the group consisting of methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, cyano, and carbamoyl, or Rl and R2 form in combination a cyclic imide, and + is a phenyl radical). The compounds according to the present invention are characterized in that (1) as shown in Table 1, they are respectively intermediates of important amino acids and capable of being induced into several of amino acids, and (2) employ benzophenone which is stable as a protecting agent of amino groups and capable of being used for recycling, and (3) are intermediates of a-amino acids having functional groups. Accordingly, the compounds of the present invention have advantages as follows. (1) The novel compounds of the present invention can easily be converted into a -amino acids having functional groups, for example, glutamine, ornithine, proline, glutamic acid, tryptophane, etc., by the necessary chemical treatments and successive hydrolysis in the presence of an acid and then of a base, or in the presence of a base and then of an acid. As has also been stated previously, it is extremely difficult and also inefficient to introduce functional groups into the intermediates of amino acids, after the formation of the main chain. While, introduction of the functional groups at early steps has a possibility of giving rise to side reactions, with consequent reduction of the yield on the whole. According to the present invention, the problems as described above have simultaneously been solved,and it has been made possible to produce amino acids in a high yield. (2) During the hydrolysis of the compounds of formula (I), benzophenone is formed as a by-product. Since benzophenone has no active hydrogen in its molecule, it is stable both thermally and chemically as compared with benzaldehyde, acetophenone, etc., and therefore, may be recycled and reused as a starting material for the production of the Schiff bases usable in the present invention. This is one of the specific features of the present invention. (3) Furthermore, since the compounds according to the present invention employ benzophenone as the protecting agent of amino groups, hydrolysis and other side reactions may be advantageously suppressed, and thus, reaction points aimed at can be specified. (4) Consequently, it is possible to manufacture the compounds of the present invention in a very high yield.
