Description
本発明は、新規なピロリン酸エステル化合物、ビスリン酸エステル化合物及び触媒に関する。 The present invention relates to a novel pyrophosphate ester compound, a bisphosphate ester compound and a catalyst.
近年、リン酸エステル化合物をブレンステッド酸触媒として用いる反応が報告されている。例えば、特許文献１では、リン酸エステル化合物である３，３’−ジアリール−１，１’−ビナフチル−２，２’−ジイル ハイドロジェンホスフェートを、マンニッヒ反応やヒドロホスホリル化反応、アザ ディールスアルダー反応などの触媒として利用している。 In recent years, reactions using phosphate ester compounds as Bronsted acid catalysts have been reported. For example, in Patent Document 1, 3,3′-diaryl-1,1′-binaphthyl-2,2′-diyl hydrogen phosphate, which is a phosphate ester compound, is converted into Mannich reaction, hydrophosphorylation reaction, aza diels alder reaction. It is used as a catalyst.
しかしながら、これまでに知られているリン酸エステル化合物は、酸性度があまり高くなかったため、例えばアルデヒドやケトンなどのカルボニル化合物を十分活性化することができなかった。そのため、基質一般性が十分とはいえなかった。 However, since the phosphoric acid ester compounds known so far have not been so acidic, carbonyl compounds such as aldehydes and ketones cannot be activated sufficiently. Therefore, it cannot be said that the generality of the substrate is sufficient.
本発明はこのような課題を解決するためになされたものであり、新規なピロリン酸エステル化合物やビスリン酸エステル化合物を提供することを主目的とする。 The present invention has been made to solve such problems, and has as its main object to provide a novel pyrophosphate ester compound and a bisphosphate ester compound.
本発明者らは、３，３’位に置換基を有するＢＩＮＯＬ誘導体（ＢＩＮＯＬは１，１’−ビ−２−ナフトールの略）に対して、水素化ナトリウム及び塩化ジアリルリン酸を反応させた後、アリル保護基を除去することにより、新規なビスリン酸エステル化合物を得た。また、このビスリン酸エステル化合物を塩化オキサリルと反応させることにより、新規なピロリン酸エステル化合物を得た。このようにして得られた新規なピロリン酸エステル化合物やビスリン酸エステル化合物を触媒として分子内エン反応やマンニッヒ反応を行ったところ、従来のリン酸エステル化合物を触媒とした場合に比べて活性が高いことを確認し、本発明を完成するに至った。 The present inventors reacted sodium hydride and diallyl phosphate with a BINOL derivative having a substituent at the 3,3 ′ position (BINOL is an abbreviation for 1,1′-bi-2-naphthol). By removing the allyl protecting group, a novel bisphosphate compound was obtained. Moreover, the novel pyrophosphate ester compound was obtained by making this bisphosphate ester compound react with oxalyl chloride. When the intramolecular ene reaction or Mannich reaction was carried out using the novel pyrophosphate ester compound or bisphosphate ester compound thus obtained as a catalyst, the activity was higher than in the case where a conventional phosphate ester compound was used as the catalyst. This was confirmed and the present invention was completed.
本発明のピロリン酸エステル化合物は、式（１）で表されるものである。但し、式（１）中、Ｒは、アリール基、有機シリル基又はハロゲン原子である。 The pyrophosphate ester compound of the present invention is represented by the formula (1). However, in Formula (1), R is an aryl group, an organic silyl group, or a halogen atom.
本発明のビスリン酸エステル化合物は、式（２）で表されるものである。但し、式（２）中、Ｒは、アリール基、有機シリル基又はハロゲン原子である。 The bisphosphate compound of the present invention is represented by the formula (2). However, in Formula (2), R is an aryl group, an organic silyl group, or a halogen atom.
本発明の新規なピロリン酸エステル化合物やビスリン酸エステル化合物は、分子内に複数のリン酸水酸基を有するため、従来のリン酸エステル化合物に比べて酸性度が高い。そのため、カルボニル化合物やイミン化合物などを活性化する能力が高い。また、配位子としても有用性が期待される。更に、ビナフチル骨格を有するため、キラルなピロリン酸エステル化合物やビスリン酸エステル化合物とすることもできる。 Since the novel pyrophosphate ester compound and bisphosphate ester compound of the present invention have a plurality of phosphate hydroxyl groups in the molecule, the acidity is higher than that of conventional phosphate ester compounds. Therefore, the ability to activate carbonyl compounds and imine compounds is high. In addition, it is expected to be useful as a ligand. Furthermore, since it has a binaphthyl skeleton, it can be a chiral pyrophosphate ester compound or bisphosphate ester compound.
本発明のピロリン酸エステル化合物は、上記式（１）で表されるものであり、Ｒは、アリール基、有機シリル基又はハロゲン原子である。また、本発明のビスリン酸エステル化合物は、上記式（２）で表されるものであり、Ｒは、アリール基、有機シリル基又はハロゲン原子である。 The pyrophosphate ester compound of the present invention is represented by the above formula (1), and R is an aryl group, an organic silyl group or a halogen atom.

３．各種反応例
３−１．分子内エン反応（その１）
シトロネラールの分子内エン反応について、化合物Ａ１〜Ａ３を触媒に用いた場合と、従来公知のリン酸エステル化合物Ｃ（表１の欄外参照）を触媒に用いた場合との活性を比較した。化合物Ａ１を触媒に用いた場合の具体的手順を以下に説明する。3. Various reaction examples 3-1. Intramolecular ene reaction (part 1)
Regarding the intramolecular ene reaction of citronellal, the activity was compared between the case where the compounds A1 to A3 were used as the catalyst and the case where the conventionally known phosphate ester compound C (see the column in Table 1) was used as the catalyst. A specific procedure when Compound A1 is used as a catalyst will be described below.
直前に調製した化合物Ａ１（０．０１ｍｍｏｌ）のジクロロメタン溶液（２ｍＬ）に対して、−７８℃にてシトロネラール（０．０３６ｍＬ，０．２ｍｍｏｌ）を加えて、２４時間撹拌した。反応溶液に対してトリエチルアミン（０．１ｍＬ）を加えて反応を停止した後、減圧下で溶媒を除去した。得られた粗生成物をシリカゲルカラムクロマトグラフィー（ヘキサン−酢酸エチル＝２０：１）で精製することにより、環化生成物（２５．６ｍｇ，８３％収率）を得た。この環化生成物は既知化合物である。その構造は，ＮＭＲスペクトルを文献記載のデータと比較することにより確認した。 Citronellal (0.036 mL, 0.2 mmol) was added at −78 ° C. to a dichloromethane solution (2 mL) of compound A1 (0.01 mmol) prepared immediately before, and the mixture was stirred for 24 hours. After the reaction was stopped by adding triethylamine (0.1 mL) to the reaction solution, the solvent was removed under reduced pressure. The resulting crude product was purified by silica gel column chromatography (hexane-ethyl acetate = 20: 1) to obtain a cyclized product (25.6 mg, 83% yield). This cyclization product is a known compound. The structure was confirmed by comparing the NMR spectrum with the data described in the literature.
同様の分子内エン反応を、化合物Ａ２，Ａ３，Ｃを触媒に用いて行った。それらの結果を表１に示す。なお、表１には反応条件も記載した。表１から、化合物Ａ１〜Ａ３を触媒に用いた場合には、化合物Ｃを触媒に用いた場合に比べて活性がかなり高いことがわかる。 A similar intramolecular ene reaction was carried out using compounds A2, A3 and C as catalysts. The results are shown in Table 1. Table 1 also shows the reaction conditions. From Table 1, it can be seen that when the compounds A1 to A3 are used as the catalyst, the activity is considerably higher than when the compound C is used as the catalyst.
３−２．分子内エン反応（その２）
上記３−１のシトロネラールの代わりに、３，３，７−トリメチル−６−オクテナールを用いた以外は、上記３−１と同様にして分子内エン反応を行った。それらの結果を表２に示す。なお、表２には反応条件も記載した。表２から明らかなように、化合物Ａ１〜Ａ３は優れた触媒活性を示したのに対して、化合物Ｃを触媒に用いた場合には生成物がほとんど得られなかった。また、反応温度を−７８℃としたところ、触媒活性は化合物Ａ２，Ａ３が化合物Ａ１よりも高い触媒活性を示した。このことから、ＢＩＮＯＬの３，３’位に無置換のフェニル基が結合している場合よりも置換基を有するフェニル基が結合している場合の方が高い触媒活性を示すことが示唆された。3-2. Intramolecular ene reaction (part 2)
Intramolecular ene reaction was carried out in the same manner as in 3-1, except that 3,3,7-trimethyl-6-octenal was used in place of the citronellal of 3-1. The results are shown in Table 2. Table 2 also shows the reaction conditions. As is clear from Table 2, compounds A1 to A3 showed excellent catalytic activity, whereas when compound C was used as a catalyst, almost no product was obtained. Further, when the reaction temperature was -78 ° C, the catalytic activities of the compounds A2 and A3 were higher than those of the compound A1. From this, it was suggested that when the phenyl group having a substituent is bonded to the 3,3′-position of BINOL, a higher catalytic activity is exhibited when the phenyl group having a substituent is bonded. .

イミンに対するアミドのマンニッヒ反応について、化合物Ａ１，Ｂ１を触媒に用いた場合と、従来公知のリン酸エステル化合物Ｃを触媒に用いた場合との活性を比較した。化合物Ａ１を触媒に用いた場合の具体的手順を以下に説明する。3-3. Mannich Reaction Regarding the Mannich reaction of amides with imines, the activity was compared between the case where compounds A1 and B1 were used as a catalyst and the case where a conventionally known phosphate ester compound C was used as a catalyst. A specific procedure when Compound A1 is used as a catalyst will be described below.
直前に調製した化合物Ａ１（０．０３ｍｍｏｌ）のジクロロメタン溶液（２ｍＬ）にモレキュラーシーブス４Ａ（３２３ｍｇ）を加え、０℃に冷却した。この溶液に、４−クロロベンズアミド（３２ｍｇ，０．２ｍｍｏｌ）およびＮ−（ベンジルオキシカルボニル）ベンズアルジミン（７４ｍｇ，０．３ｍｍｏｌ）を加え、０℃にて３０分間撹拌した。反応溶液に水を加えて反応を停止した後、ジクロロメタンで抽出した。有機層を合わせて飽和食塩水で洗浄し、無水炭酸ナトリウムで乾燥後、減圧濃縮した。得られた粗生成物をシリカゲルカラムクロマトグラフィー（クロロホルム−酢酸エチル＝５０：１→３０：１）で精製することにより、目的とする付加体（７８．５ｍｇ，＞９９％収率）を得た。この付加体は既知化合物である。その構造は，ＮＭＲスペクトルを文献記載のデータと比較することにより確認した。 Molecular sieves 4A (323 mg) was added to a dichloromethane solution (2 mL) of compound A1 (0.03 mmol) prepared immediately before, and the mixture was cooled to 0 ° C. To this solution, 4-chlorobenzamide (32 mg, 0.2 mmol) and N- (benzyloxycarbonyl) benzaldimine (74 mg, 0.3 mmol) were added, and the mixture was stirred at 0 ° C. for 30 minutes. Water was added to the reaction solution to stop the reaction, followed by extraction with dichloromethane. The organic layers were combined, washed with saturated brine, dried over anhydrous sodium carbonate, and concentrated under reduced pressure. The resulting crude product was purified by silica gel column chromatography (chloroform-ethyl acetate = 50: 1 → 30: 1) to obtain the desired adduct (78.5 mg,> 99% yield). . This adduct is a known compound. The structure was confirmed by comparing the NMR spectrum with the data described in the literature.
同様のマンニッヒ反応を、化合物Ｂ１，Ｃを触媒に用いて行った。それらの結果を表３に示す。なお、表３には反応条件も記載した。表３から、化合物Ｃに比べて化合物Ａ１，Ｂ１の触媒活性、特に化合物Ａ１の触媒活性が高かった。このことから、ビスリン酸エステル化合物よりもピロリン酸エステル化合物の方が高い触媒活性を示すことが示唆された。 A similar Mannich reaction was performed using compounds B1 and C as catalysts. The results are shown in Table 3. Table 3 also shows the reaction conditions. From Table 3, compared with the compound C, the catalytic activity of compound A1, B1, especially the catalytic activity of compound A1 was high. This suggests that the pyrophosphate compound exhibits higher catalytic activity than the bisphosphate compound.

Regarding the Friedel-Crafts reaction between aldimine and cresol, the activity was compared between when the compounds A1 to A6 were used as the catalyst and when the conventionally known phosphate ester compound C was used as the catalyst. A specific procedure when compound A1 is used as a catalyst (entry 2 in Table 4) will be described below.
直前に調製した化合物Ａ１（０．０１ｍｍｏｌ）の塩化メチレン溶液（１ｍＬ）に対して、Ｎ−ベンジルオキシカルボニル（Ｃｂｚ）アルジミン（２ｍｍｏｌ）を室温で溶解させた後、ｏ−クレゾール（３ｍｍｏｌ）の塩化メチレン溶液を０℃で添加し、３時間撹拌した。反応溶液に対して水（２ｍＬ）を加えて反応を停止した後、酢酸エチルで分液し、減圧下で溶媒を除去した。得られた粗生成物をシリカゲルカラムクロマトグラフィー（ヘキサン−酢酸エチル＝１０：１→５：１）で精製することにより、パラ位に選択的なフリーデル−クラフツ反応の生成物を収率８５％、光学収率４％ｅｅで得た。この生成物のスペクトルデータは以下のとおり。 N-benzyloxycarbonyl (Cbz) aldimine (2 mmol) was dissolved at room temperature in a methylene chloride solution (1 mL) of compound A1 (0.01 mmol) prepared immediately before, and o-cresol (3 mmol) was salified. Methylene solution was added at 0 ° C. and stirred for 3 hours. Water (2 mL) was added to the reaction solution to stop the reaction, followed by liquid separation with ethyl acetate, and the solvent was removed under reduced pressure. The obtained crude product was purified by silica gel column chromatography (hexane-ethyl acetate = 10: 1 → 5: 1) to obtain a product of the Friedel-Crafts reaction selective for the para position in a yield of 85%. And an optical yield of 4% ee. The spectral data of this product is as follows.

同様のフリーデル−クラフツ反応を、化合物Ａ２〜Ａ６，Ｃを触媒に用いて行った。それらの結果を表４に示す。表４から、化合物Ｃに比べて化合物Ａ１〜Ａ６の触媒活性がかなり高く、フェノールの４位で付加した生成物が選択的に得られた。また、化合物Ａ４〜Ａ６（特にＡ５）を用いた場合に良好なエナンチオ選択性が発現することがわかった。更に、触媒に化合物Ａ５を用い、溶媒にクロロホルムを用いた場合（表４のエントリー７）、より高いエナンチオ選択性を示した。なお、溶媒に二塩化エチレン、トルエン、トリフルオロメチルベンゼン、ニトロエタンを用いたところ、いずれもフリーデル−クラフツ反応の生成物が得られたが、クロロホルムを用いた場合の成績が最も良かった。 A similar Friedel-Crafts reaction was performed using compounds A2 to A6 and C as catalysts. The results are shown in Table 4. From Table 4, the catalytic activity of the compounds A1 to A6 was considerably higher than that of the compound C, and the product added at the 4-position of phenol was selectively obtained. Moreover, it turned out that favorable enantioselectivity is expressed when the compounds A4 to A6 (particularly A5) are used. Further, when compound A5 was used as the catalyst and chloroform was used as the solvent (entry 7 in Table 4), higher enantioselectivity was exhibited. When ethylene dichloride, toluene, trifluoromethylbenzene, or nitroethane was used as the solvent, the Friedel-Crafts reaction product was obtained, but the results with chloroform were the best.
