Description
本発明は、光学分割材料、不斉認識材料、pHセンサー等として有用な塩基性アミノ酸を有する新規ならせん状ポリマー、その製造方法および使用に関する。 The present invention relates to a novel helical polymer having a basic amino acid useful as an optical resolution material, an asymmetric recognition material, a pH sensor, and the like, a production method thereof, and use thereof.
アミノ酸はシンプルな構造ながらアミノ基、カルボキシ基はもとより、各種のアルキル基、アリール基、さらには水酸基、メルカプト基などの修飾可能な官能基を複数個分子内に有する、安価で高純度の光学活性源として有機合成の分野で広く用いられている。アミノ酸から誘導される合成高分子であるペプチドは、タンパク質のモデル化合物として研究されており、その高次構造ならびに種々の反応の触媒作用が検討されている。アミノ酸は医薬品、農薬、飼料、調味料、甘味料、健康栄養食品、香粧品の原料として幅広く用いられており、近年の発酵法、化学合成法の目覚ましい発展により高い光学純度のものが安価に入手可能である。このような状況に鑑み,発明者らはアミノ酸を生体関連機能のみならず、様々な化学的機能を発現する機能性高分子の材料として位置付け検討してきた(非特許文献1)。アミノ酸のポリマーとしてはペプチドが一般的であるが、発明者らはアミノ酸構造を有するアセチレン誘導体がロジウム触媒により効率よく重合し、側鎖にアミノ酸を規則正しく配列する一方向巻き優先のらせん構造を形成すること、このらせんは外部刺激(熱、光、溶媒)により巻き方向を反転させる、あるいはランダム構造に転移すること、また、幾つかのポリマーは不斉認識能、金属捕捉能を有すること、このポリマーの金属錯体は不斉水素移動反応を触媒することを見出し、これによりこれらのアミノ酸のポリマーが光学分割材料、不斉認識材料、pHセンサー等として有用と考えられる。しかしながら、従来に報告されているアミノ酸を側鎖に有するらせんポリマーの安定性は必ずしも高くなく、また酸に応答してその高次構造を転換するものはいまだ報告されていない。 Amino acid has simple structure but amino acid, carboxy group, various alkyl groups, aryl groups, hydroxyl group, mercapto group, etc. As a source, it is widely used in the field of organic synthesis. Peptides, which are synthetic macromolecules derived from amino acids, have been studied as protein model compounds, and their higher-order structures and catalysis of various reactions have been studied. Amino acids are widely used as raw materials for pharmaceuticals, agrochemicals, feeds, seasonings, sweeteners, health nutrition foods, and cosmetics. Due to the remarkable development of recent fermentation and chemical synthesis methods, amino acids with high optical purity are available at low cost. Is possible. In view of such circumstances, the inventors have positioned amino acids as materials for functional polymers that express not only biological functions but also various chemical functions (Non-Patent Document 1). Peptides are common as polymers of amino acids, but the inventors efficiently polymerize acetylene derivatives having an amino acid structure with a rhodium catalyst to form a helical structure in which the amino acids are regularly arranged in the side chain in a one-way winding priority. This spiral can reverse the direction of winding by an external stimulus (heat, light, solvent) or change to a random structure, and some polymers have asymmetric recognition ability and metal capture ability. These metal complexes have been found to catalyze asymmetric hydrogen transfer reactions, and as a result, polymers of these amino acids are considered useful as optical resolution materials, asymmetric recognition materials, pH sensors and the like. However, the stability of helical polymers having amino acids in the side chain that have been reported in the past is not necessarily high, and there has not yet been reported one that changes its higher-order structure in response to acid.
本発明の目的は、上記問題に鑑み、温度変化、極性変化に対しても高い高次構造を取ることができ、かつ酸に対する応答性に優れる新規なポリマー、その製造方法および光学分割における使用を提供することにある。 In view of the above problems, an object of the present invention is to provide a novel polymer that can take a high-order structure even with respect to temperature change and polarity change, and has excellent responsiveness to acid, its production method, and use in optical resolution. It is to provide.

実施例1〜8の各モノマーをより得られたポリマーIの数平均分子量(Mn)は、4900〜12600の範囲にあり、分子量分布(Mw/Mn )は、1.59〜3.22の範囲であった(表1)。これは、重合が効率的に副反応無く進行したことを示している。 The number average molecular weight (Mn) of the polymer I obtained from each monomer of Examples 1 to 8 was in the range of 4900 to 12600, and the molecular weight distribution (M w / M n ) was in the range of 1.59 to 3.22. (Table 1). This indicates that the polymerization proceeded efficiently without side reactions.
また、温度変化、極性変化に対しても高い高次構造を取ることができる。表2に示すように、各種溶媒中でモノマーに比べて一桁大きい比旋光度を示すこと、図1に示すようにいずれのポリマーもクロロホルム中およびTHF中、主鎖ポリアセチレンの共役に基づくCDシグナル、UV-可視シグナルを400nm近辺に示したことから、主鎖がらせん構造を形成していることが分かる。図2、図3に示すように、これらのシグナルは0〜60℃の温度範囲ではほとんど強度変化を示さず、ポリマーのらせん構造が熱に対して安定であることが分かる。図4に示すように、ポリマーのクロロホルム溶液にメタノールを添加した場合、Poly(1)、Poly(2)、Poly(5)、Poly(6)はほとんどCDシグナル、UV-可視シグナルの変化を示さず、極性溶媒に対して安定ならせんであることが分かる。 In addition, a high-order structure can be taken with respect to temperature change and polarity change. As shown in Table 2, the specific optical rotation is an order of magnitude greater than that of the monomer in various solvents, and as shown in FIG. 1, the CD signals based on the conjugation of the main chain polyacetylene in chloroform and THF as shown in FIG. The UV-visible signal was shown around 400 nm, indicating that the main chain forms a helical structure. As shown in FIGS. 2 and 3, these signals show almost no intensity change in the temperature range of 0 to 60 ° C., indicating that the helical structure of the polymer is stable to heat. As shown in Fig. 4, when methanol was added to the polymer chloroform solution, Poly (1), Poly (2), Poly (5), and Poly (6) showed almost no change in CD signal and UV-visible signal. It can be seen that the helix is stable against polar solvents.
