Definitions
- the present invention relates to a combination of suitable solvents used in a "compatible one-phase organic solvent system", and particularly a solvent suitable for a peptide synthesis process and a chemical process for imparting electric energy such as an electrochemical process. It is a technology that provides a combination of these technologies and dramatically improves the efficiency of such chemical processes.
- the “solvent combination” is referred to as a “solvent set”.
- the solvent set is a combination of a relatively low-polarity first solvent and a relatively high-polarity second solvent, and each of these first and second solvents may be a mixed solvent of a plurality of solvents. Of course, a single solvent may be used.
- Patent Document 1 An example of the use of this solvent set is a peptide synthesis reaction in a liquid phase that is not inferior to conventional solid phase peptide synthesis (see Non-Patent Document 1 and Patent Document 2).
- Patent Document 2 Another application example is a selective oxidation reaction process using this solvent (see Patent Document 1, paragraphs 0024 to 0025).

- 1 DMI is a kind of cyclic urea compound and is a colorless, transparent, highly polar aprotic polar solvent.
- DMI is more stable in the presence of acid and acid than general aprotic polar solvents, and is particularly excellent in alkali resistance and acid resistance even at high temperatures.
- DMI has a high boiling point and a high flash point, and has a low freezing point (boiling point: 25.5 ° C, flash point: 120 ° C, freezing point: 8.2 ° C).
- DMI has a strong dissolving power for various inorganic and organic compounds, and has the effect of promoting reactions and suppressing side reactions due to its “high dielectric constant” and “solvation effect”.
- Typical applications include 1) pharmaceuticals, agricultural chemicals, dyes, synthetic solvents for high value-added products such as pigments, 2) cleaning agents for electronic components and molds, 3) polymerization solvents for high molecular compounds, etc. (See Patent Documents 3, 4, and 5).
- the first solvent is basically a low-polarity organic solvent, and a group of compounds constituting the solvent includes alkanes, cycloalkanes, algens, alkynes, aromatic compounds, and the like. Among them, cycloalkane compounds are preferred, and "cyclohexane" is mentioned as a particularly preferred compound. It is speculated that the conversion of the chair-boat conformer of cyclohexane is related to the relatively mild thermal conditions that occur with other solvents. Cyclohexane has a relatively high melting point of 6.5, and has the advantage that it can solidify and separate the product after the reaction, and has the merit in the final recovery step, which is also preferable from this aspect. ing.
- the organic solvent constituting the other solvent or the mixed solvent (second solvent) combined with the first solvent is basically a highly polar organic solvent. It is described that preferred are those composed of at least one selected from the group consisting of nitroalkanes, nitriles, alcohols, alkyl halides, amide compounds and sulfoxides.
- the second solvent is, specifically, the alkyl group of the nitroalkane has carbon atoms. Is 1, 2 or 3, the carbon number of the nitrile alkyl group is 1, 2 or 3, and the amide compound is the alkyl group of N-dialkyl or N-monoalkylamido and the acryl group or formyl group.

- the volume ratios of CH and NA are 1: 5, 2: 5, 1: 1,
- the first solvent, cyclohexane (CH), and the second solvent are fixed at an equal volume of 1: 1 (50% by volume each).
- the second solvent is nitromethane (NM).
- NM nitromethane
- NE nitroethane and nitroethane
- PN acetonitrile
- DMF dimethylformamide
- DMA dimethylacetamide
- the compatibilization temperature changes between 20 ° C and 60 ° C depending on the first and second solvent configurations.
- the compatibilization temperature (separation temperature) of both solvents can be increased by 20 °. It can be seen that the temperature can be appropriately changed in the range of C to 60 ° C.
- the chemical process using a solvent set is not limited to a specific process, and may be a liquid-phase peptide synthesis process in which amino acids of Patent Document 2 are sequentially added,
- a general electrochemical reaction process may be used.
- the process is not limited to the electrochemical reaction process, but may be a process in which electric energy is provided to promote a chemical reaction.
- Diels Alder Die 1 s -Alder
- non-patent literature 2 and non-patent literature 3 generally describe technical standards for polarity or permittivity. That is, the experimental evaluation of the polarity (ET (30)) may be performed according to the method described in Non-Patent Document 3, and the experimental evaluation of the dielectric constant may be performed according to the method described in Non-Patent Document 2. .
- the polarity (ET (30)) should be 25 or more, or the dielectric constant should be 20 or more. Conversely, if the conditions for a low-polarity solvent are expressed in accordance with these, the dielectric constant is 0 to 15 or the polarity (ET (30)) is less than 20.

- An object of the present invention is to provide a more suitable solvent set used as a “compatible-multiphase organic solvent system”.
- the compatibilization temperature of a solvent system was lowered by using a mixed solvent of a plurality of solvents, but the task is to achieve this with a single solvent.

- the cyclic urea (urea) compound is a dialkylimidazolidinone in which the total number of carbon atoms in the two alkyl groups is 2 or more (5 or more in total carbon atoms). There is no particular upper limit on the total number of carbon atoms in the compound, but usually 30 or less are used.
- the most preferred second solvent is DMI (dimethylimidazolidinone).
- Fig. 1 shows an example of a cyclic force (carbonate ester) compound (Fig. 1 (a)), an example of a cyclic carbamate (urethane) compound (Fig. 1 (b)), and an optimal example of a cyclic urethane.

Further, similar effects have been found not only on DMI but also on general carbonate (carbonate ester) compounds or carbamate (urethane) compounds or perrea (urea) compounds or cyclic amides or cyclic ketoamines.
- the effect is that the compatibilization temperature (separation temperature) of the solvent system was reduced by using a mixed solvent of multiple solvents in the past, but this can be achieved with a single solvent, for example, a single DMI.

- the compatibilization temperature (separation temperature) of the solvent system could be sufficiently reduced. This is advantageous for peptide synthesis and the like.

- the dielectric constant of the first solvent may be 0 to 15 or the polarity (E T (30)) of the first solvent may be less than 20. Examples of the chemical process are shown below.

- the solvent has a polarity (ET (30)) of less than 20.
- a mixed solution of cyclohexane and DMI was prepared at 20 ° C. and 1 atm. At this time, the organic solvent system separated into two phases. To this mixed solution, 200 milligrams of lithium perchlorate as a supporting electrolyte and 10 milligrams of hexadetinthiol as an electrolytic substrate were added.

Round trip to 2-2.0 Porto (Cyclic Portummetry), The potential was changed at 100 milliports per second, and the corresponding current was measured. At this temperature, the solvent system was in the state of a separated solvent system. As a result, oxidation of hexadecanethiol hardly occurred, and no remarkable peak indicating oxidation of the thiol group was observed.
