Description

本発明は新規化合物に関する。さらに詳しくは、新規化合物を用いた縮合剤及び該縮合剤を用いた生成物や自己修復能を有するハイドロゲル(以下、単にゲルと示す場合がある)等の製造方法に関する。 The present invention relates to novel compounds. More specifically, it relates to a method for producing a condensing agent using a novel compound, a product using the condensing agent, a hydrogel having a self-repairing ability (hereinafter, sometimes simply referred to as a gel), and the like.

従来から縮合剤を用いて縮合反応を行うことにより、様々な生成物を製造することが知られている。
例えば、特許文献1では2-クロロ-4,6-ジメトキシ-1,3,5-トリアジン(CDMT)と4-メチルモルホリン(NMM)を加えて得られる4級アンモニウム塩(4,6-ジメトキシ-1,3,5-トリアジン-2-イル)メチルモルホリニウムクロライド(DMT-MM)を縮合剤として用い、ゲル状のポリ-γ-アミノ酸架橋体を生成物として得たことが記載されている。
It is conventionally known to produce various products by carrying out a condensation reaction using a condensing agent.
For example, in Patent Document 1, a quaternary ammonium salt (4,6-dimethoxy-) obtained by adding 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) and 4-methylmorpholine (NMM). 1,3,5-triazin-2-yl)methylmorpholinium chloride (DMT-MM) is used as a condensing agent, and it is described that a gel-like poly-γ-amino acid crosslinked product was obtained as a product. ..

また、縮合剤等を用いて製造される自己修復能を有する高分子材料は、摩擦や衝撃等により穴や切断面が生じても再結合して元通りに戻る性質を有することから、接着剤、塗料やコーティングフィルム、ハードコート剤の代替、衝撃吸収材等として有用である。そのため、様々な高分子材料が開発されてきた。
このような高分子材料は、モノマーを重合させて製造されることも多く、例えば、特許文献2ではホスト基含有モノマー、ゲスト基含有モノマー及びアクリル系モノマーの水系溶媒溶液を製造し、このモノマーを共重合させることにより自己修復性及び形状記憶性を有するゲルを製造することが開示されている。また、特許文献3ではN-(1-アダマンチル)アクリルアミドを用い、アクリルアミド、過硫酸アンモニウム及びN,N,N,N-テトラメチルエチレンジアミンを加えて25℃で24時間重合を行うことで自己修復能を有するβ-CD/ゲスト基含有重合体を得たことが開示されている。
Further, a polymer material having a self-repairing ability produced by using a condensing agent has the property of recombining and returning to the original state even if a hole or a cut surface is formed due to friction or impact. It is also useful as a substitute for paints and coating films, hard coating agents, and as an impact absorbing material. Therefore, various polymeric materials have been developed.
Such a polymer material is often produced by polymerizing a monomer. For example, in Patent Document 2, an aqueous solvent solution of a host group-containing monomer, a guest group-containing monomer and an acrylic monomer is produced and It is disclosed that a gel having self-repairing property and shape memory property is produced by copolymerization. Further, in Patent Document 3, N-(1-adamantyl)acrylamide is used, and acrylamide, ammonium persulfate, and N,N,N,N-tetramethylethylenediamine are added, and polymerization is carried out at 25° C. for 24 hours to improve self-repair ability. It is disclosed that the obtained β-CD/guest group-containing polymer was obtained.

DMT-MM等の公知の縮合剤は生分解性が低く、安全性等に問題があった。そこで、本発明者らは本発明において、従来の縮合剤と比べて安全性が高い新規の縮合剤等の提供を試みた。 Known condensing agents such as DMT-MM have low biodegradability and have problems in safety and the like. Therefore, the inventors of the present invention tried to provide a novel condensing agent or the like having higher safety than the conventional condensing agents in the present invention.

The produced target product B was obtained. The progress of this reaction was confirmed by TLC in the same manner as in Examples 2-1 and 1) above. Ethyl acetate was added to this reaction solution, which was then transferred to a separating funnel and washed with a saturated sodium carbonate aqueous solution. Then, the ethyl acetate layer was subjected to LC-MS. As a result, a peak having the same molecular weight as that of Target B was confirmed.

なお、比較としてMCTCD-NMM水溶液の替わりにMCTCD水溶液10mL(内、MCT-β-CDを1.59mmol含む)を用いて同様の反応を行った場合、目的物Bは得られなかった。従ってこの結果より、実施例1と同様の方法により製造した新規化合物(MCTCD-NMM)を縮合剤とするにより、Ad-COOHとPAの縮合反応が起こることが確認できた。 As a comparison, when the same reaction was carried out using 10 mL of MCTCD aqueous solution (including 1.59 mmol of MCT-β-CD) instead of the MCTCD-NMM aqueous solution, the target product B was not obtained. Therefore, from this result, it was confirmed that the condensation reaction of Ad-COOH and PA occurs when the novel compound (MCTCD-NMM) produced by the same method as in Example 1 was used as the condensing agent.

1)実施例1と同様の方法により製造したMCTCD-NMM水溶液 100mL(内、MCT-β-CDを16.0mmol含む)と0.2Mリン酸ナトリウム緩衝液(pH8.0)100mLをバイアル瓶に量り取り、TA 2.172g(16.0mmol)を添加し、溶解させた。その後、室温で25時間撹拌した。この反応の進行は、TLCにより確認した。TLCの展開溶媒は、ヘキサン:酢酸エチル:メタノール=2.5:1:1(酢酸数滴)を用いた。
2)上記1)により撹拌して得た反応液にPA 9.664g(79.7mmol)を添加し、室温で18時間撹拌することで下記の反応式(8)により生成される4-Methyl-N-(2-phenylethyl)benzamideを得た。この反応の進行は、TLCにより確認した。TLCの展開溶媒は、ヘキサン:酢酸エチル:メタノール=2.5:1:1(酢酸数滴)を用いた。この反応液に酢酸エチルを加え、分液ろうとに移し、飽和炭酸ナトリウム水溶液、10%クエン酸水および水で洗浄し、ろ過後、有機層を硫酸マグネシウムで乾燥させた。その後ろ過し、エバポレーターで酢酸エチルを揮発させ、粉末を得た。これをLC-MSに供したところ、4-Methyl-N-(2-phenylethyl)benzamideと同分子量のピークが確認できた。

Then, the mixture was filtered, and ethyl acetate was volatilized with an evaporator to obtain a powder. When this was subjected to LC-MS, a peak with the same molecular weight as 4-Methyl-N-(2-phenylethyl)benzamide could be confirmed.

なお、比較としてMCTCD-NMM水溶液の替わりにMCTCD水溶液10mL(内、MCT-β-CDを1.59mmol含む)を用いて同様の反応を行った場合、4-Methyl-N-(2-phenylethyl)benzamideはほとんど得られなかった。従ってこの結果より、実施例1と同様の方法により製造した新規化合物(MCTCD-NMM)を縮合剤とするにより、TAとPAの縮合反応が起こることが確認できた。 As a comparison, when 10 MmL of MCTCD aqueous solution (including 1.59 mmol of MCT-β-CD) was used instead of MCTCD-NMM aqueous solution and the same reaction was performed, 4-Methyl-N-(2-phenylethyl)benzamide was obtained.

Condensation reaction of TA and BA 1) 80 mL of MCTCD-NMM aqueous solution (including 12.8 mmol of MCT-β-CD) produced by the same method as in Example 1 and 80 mL of 0.2 M sodium phosphate buffer (pH 8.0) Was weighed into a vial and TA 1.737 g (12.8 mmol) was added and dissolved. Then, the mixture was stirred at room temperature for 25 hours. The progress of this reaction was confirmed by TLC. As a developing solvent for TLC, hexane:ethyl acetate:methanol=2.5:1:1 (a few drops of acetic acid) was used.
2) To the reaction solution obtained by stirring in 1) above, 6.836 g (63.8 mmol) of BA was added, and the mixture was stirred at room temperature for 2 hours to produce N-Benzyl-4-produced by the following reaction formula (9). I got methylbenzamide. The progress of this reaction was confirmed by TLC. As a developing solvent for TLC, hexane:ethyl acetate:methanol=2.5:1:1 (a few drops of acetic acid) was used. Ethyl acetate was added to this reaction solution, which was then transferred to a separating funnel, washed with a saturated sodium carbonate aqueous solution, 10% citric acid water and water, filtered, and the organic layer was dried over magnesium sulfate. Then, the mixture was filtered, and ethyl acetate was volatilized with an evaporator to obtain a powder. When this was subjected to LC-MS, a peak with the same molecular weight as N-Benzyl-4-methylbenzamide was confirmed. In addition, 1 H NMR measurement confirmed that the reaction product was N-Benzyl-4-methylbenzamide.

なお、比較としてMCTCD-NMM水溶液の替わりにMCTCD水溶液10mL(内、MCT-β-CDを1.59mmol含む)を用いて同様の反応を行った場合、N-Benzyl-4-methylbenzamideは得られなかった。従ってこの結果より、実施例1と同様の方法により製造した新規化合物(MCTCD-NMM)を縮合剤とするにより、TAとBAの縮合反応が起こることが確認できた。 For comparison, N-Benzyl-4-methylbenzamide was not obtained when the same reaction was carried out using 10 mL of MCTCD aqueous solution (including 1.59 mmol of MCT-β-CD) instead of MCTCD-NMM aqueous solution. .. Therefore, from this result, it was confirmed that the condensation reaction of TA and BA occurs when the novel compound (MCTCD-NMM) produced by the same method as in Example 1 was used as the condensing agent.

ネガティブコントロールとしてMCTCD水溶液を用いてTAとPAを反応させた場合もTAとBAを反応させた場合も目的物はほとんど生成されなかった。また、MCTCD-NMMの調製の際に添加したNMMと同濃度のNMM水溶液を用いた場合はTAとPAを反応させた場合もTAとBAを反応させた場合も目的物がまったく生成されなかった。
従ってこれらの結果より、カルボン酸とアミンの縮合反応を起こすには、実施例1と同様の方法により製造した新規化合物(MCTCD-NMM)を縮合剤とすることが重要であることが確認できた。
As a negative control, the target product was scarcely produced when TA and PA were reacted with TA and BA using MCTCD aqueous solution. In addition, when the NMM aqueous solution of the same concentration as the NMM added during the preparation of MCTCD-NMM was used, neither the reaction of TA with PA nor the reaction of TA with BA produced the desired product at all. ..
Therefore, from these results, it was confirmed that it is important to use the novel compound (MCTCD-NMM) produced by the same method as in Example 1 as the condensing agent in order to cause the condensation reaction of the carboxylic acid and the amine. ..
