【発明の属する技術分野】
本発明は、トイレタリー製品や香粧品などの香料添加製品に用いる香料成分として、より特徴的で香質で強い香気を有する香料組成物に関する。
【0002】
【従来の技術】
2−tert−ブチルシクロヘキサノールは広く知られた香料物質であり、シス体とトランス体の2種類の幾何異性体が存在し、更に分子内に2つの不斉炭素を有するためにシス体(以下、cis−2−tert−ブチルシクロヘキサノールと称する)として(1S,2S)−(+)−2−tert−ブチルシクロヘキサノール(以下、(1S,2S)体と称す)と(1R,2R)−(−)−2−tert−ブチルシクロヘキサノール(以下、(1R,2R)体と称す)が、トランス体として(1S,2R)−(+)−2−tert−ブチルシクロヘキサノール(以下、(1S,2R)体と称す)と(1R,2S)−(−)−2−tert−ブチルシクロヘキサノール(以下、(1R,2S)体と称す)の4種類の立体異性体が存在する。これらの香気性について、特開昭59−65031号公報によればシス体の香気はトランス体と比べて遙かに優れていることが開示されているが、シス体のうち、(1R,2R)体と(1S,2S)体の香気の違いについては全く知られていない。
【0003】
近年、トイレタリー製品や香粧品などの香料添加製品に用いる香料成分として、より特徴的な香質で強い香気を有する香料物質及び香料組成物が求められており、中でもグリーン調およびハーバル調の香りは、少量の使用で、高い香気改善効果の得られる素材が強く求められているにもかかわらず、この要求を十分満たすような素材はなかった。
【0004】
【発明が解決しようとする課題】
本発明の課題は、少量の使用で、高い香気改善効果の得られる香料素材を含有する、トイレタリー製品や香粧品などに有用な香料組成物を提供することにある。
【0005】
【課題を解決するための手段】
即ち、本発明は、
(1)(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学純度が0%eeを超えてなるcis−2−tert−ブチルシクロヘキサノールを含有してなる香料組成物、および
(2)(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学純度が20%ee以上である前記(1)記載の香料組成物、
に関する。
【0006】
【発明の実施の形態】
本発明の香料組成物は、(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学純度が0%eeを越えてなるシス体の2−tert−ブチルシクロヘキサノールを含有することを特徴とする。
ここで、(1R,2R)体の光学純度(%ee)=(1R,2R)体比率(%)−(1S,2S)体比率(%) (1)
〔式中、(1R,2R)体比率と(1S,2S)体比率は、後述の実施例1で示す光学活性カラムを使用したガスクロマトグラフィでのcis−2−tert−ブチルシクロヘキサノールに対するそれぞれの異性体の面積比率(%)で表す。〕
【0007】
本発明の香料組成物に使用されるcis−2−tert−ブチルシクロヘキサノールは、(1R,2R)体の他に(1S,2S)体を含有してもよいが、(1S,2S)体の含有量が多くなると(1R,2R)体に特徴的なフレッシュ感のあるグリーンな香気を得ることはできない。(1R,2R)体の特徴的な香気は、(1R,2R)体と(1S,2S)体との混合物中の(1R,2R)体比率が上記(1)式で表される光学純度で0%eeを超える場合に認知できるようになる。香気の点から、(1R,2R)体の光学純度は20%ee以上がより好ましく、60%ee以上がさらに好ましく、80%ee以上が特に好ましい。
【0008】
本発明の(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールは、例えば光学活性な保持層を有する液体クロマトグラフィあるいはガスクロマトグラフィでラセミ体からシス体を分離する方法、シス体の脂肪酸エステルを酵素により選択的に加水分解する方法、シス体を光学活性な包接化合物に包接させて分離する方法、(2R)−2−tert−ブチルシクロヘキサノンを光学活性配位子を有する金属触媒を用いて不斉還元する方法、シス体を光学活性な化合物(分割剤)で誘導体化して得られるジアステレオマを分離後に分割剤を除去する方法など光学活性アルコールを得るための一般的な方法で得ることができる。
【0009】
例えば、シス体を光学活性な化合物(分割剤)で誘導体化して得られるジアステレオマを分離した後に分割剤を除去する方法では、分割剤として光学活性カルボン酸、光学活性イソシアナート、光学活性酸ハライドなどラセミ体アルコールのジアステレオマ化で一般的に使用される化合物を用いることができるが、光学活性カルボン酸のエステルに変換できる光学活性カルボン酸や光学活性酸ハライドを用いることが好ましい。光学活性カルボン酸や光学活性酸ハライドとしては、(R)−(−)−2−フェニル酪酸、(1S)−(−)−カンファン酸、(R)−(+)−α−メトキシ−α−(トリフルオロメチル)フェニル酢酸、(S)−(+)−フェニルプロピオン酸及びこれらの酸ハライドなどが挙げられるが、入手のしやすさと分離の容易さから(1S)−(−)−カンファン酸あるいはその酸ハライドを用いることが好ましい。
【0010】
シス体の光学活性カルボン酸エステルは、一般的な方法、例えば実験化学講座(第4版、22巻、43から46頁)〔丸善株式会社発行〕記載の触媒を用いるエステル化反応や脱水剤を用いるエステル化反応によってシス体と光学活性カルボン酸から、あるいは実験化学講座(第4版、22巻、50から51頁)〔丸善株式会社発行〕記載の酸ハロゲン化物を用いるエステル化反応によってシス体と光学活性カルボン酸ハライドから得ることができる。得られたシス体の光学活性カルボン酸エステルのジアステレオマから例えば、カラムクロマトグラフィや再結晶などの方法により(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学活性カルボン酸エステルを分離して得ることができる。
【0011】
(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学活性カルボン酸エステルからは酸またはアルカリを用いる一般的なエステルの加水分解によって目的の(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールを得ることができる。
【0012】
(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールはまた、(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学活性カルボン酸エステルを、例えばリチウムアルミニウムヒドリド、ジイソブチルアルミニウムヒドリド、ヒドロボランなど実験化学講座(第4版、26巻、161頁)〔丸善株式会社発行〕記載の還元剤で還元して得ることもできる。
【0013】
上記のようにして得られた(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの絶対配置は、例えば、チェオらがJ.Chem.Soc.,(C),1988(1966)で報告した(1S,2S)−(+)−2−tert−ブチルシクロヘキサノールの旋光度と比較して決定することができる。
【0014】
(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールは強いフレッシュ感のあるグリーンな香気を有していることから、単独でまたは香料組成物に一般に使用される他の成分と組み合わせて、香水、オーデコロン、石鹸、シャンプー、リンス、洗剤、化粧品、スプレー製品、芳香剤など賦香を必要とする製品に広く使用できる。
【0015】
(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学純度が0%eeを超えてなるcis−2−tert−ブチルシクロヘキサノールを香料組成物中に配合する場合、その配合量は対象とする調合香料、目的とする香気などによって異なり、また目的とする香気を賦与できる量であれば特に限定されないが、一般的には香料組成物中に0.1〜50重量%、好ましくは1〜30重量%配合する。
【0016】
さらに本発明の香料組成物には、(1R,2R)−(−)−2−tert−ブチルシクロヘキサノールの光学純度が0%eeを超えてなるcis−2−tert−ブチルシクロヘキサノールに、トランス体である(1S,2R)体または(1R,2S)体の2−tert−ブチルシクロヘキサノールを混合して使用することもできる。

About.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The fragrance composition of the present invention contains cis isomer of 2-tert-butylcyclohexanol in which the optical purity of (1R, 2R)-(−)-2-tert-butylcyclohexanol exceeds 0% ee. It is characterized by.
Here, the optical purity (% ee) of the (1R, 2R) isomer = (1R, 2R) isomer ratio (%) − (1S, 2S) isomer ratio (%) (1)
[Wherein, (1R, 2R) isomer ratio and (1S, 2S) isomer ratio are the respective ratios relative to cis-2-tert-butylcyclohexanol in gas chromatography using an optically active column shown in Example 1 described later. It is expressed as an area ratio (%) of isomers. ]
[0007]
The cis-2-tert-butylcyclohexanol used in the fragrance composition of the present invention may contain a (1S, 2S) body in addition to a (1R, 2R) body, but a (1S, 2S) body. When the content of is increased, it is not possible to obtain a green fragrance with a fresh feeling characteristic of (1R, 2R). The characteristic fragrance of the (1R, 2R) body is the optical purity in which the (1R, 2R) body ratio in the mixture of the (1R, 2R) body and the (1S, 2S) body is represented by the above formula (1) It becomes possible to recognize when it exceeds 0% ee. From the viewpoint of aroma, the optical purity of the (1R, 2R) isomer is more preferably 20% ee or more, further preferably 60% ee or more, and particularly preferably 80% ee or more.
[0008]
The (1R, 2R)-(−)-2-tert-butylcyclohexanol of the present invention is a method for separating a cis isomer from a racemate by, for example, liquid chromatography or gas chromatography having an optically active retention layer, a fatty acid in the cis isomer A method of selectively hydrolyzing an ester with an enzyme, a method of separating a cis isomer by inclusion of an optically active inclusion compound, and a metal catalyst having an optically active ligand of (2R) -2-tert-butylcyclohexanone Obtained by a general method for obtaining an optically active alcohol, such as a method of asymmetric reduction using cis, a method of removing a resolving agent after separation of a diastereomer obtained by derivatizing a cis isomer with an optically active compound (resolving agent) be able to.
[0009]
For example, in a method of removing a resolving agent after separating a diastereomer obtained by derivatizing a cis isomer with an optically active compound (resolving agent), an optically active carboxylic acid, an optically active isocyanate, an optically active acid halide, etc. Although compounds generally used in diastereoisomerization of racemic alcohols can be used, it is preferable to use optically active carboxylic acids or optically active acid halides that can be converted into esters of optically active carboxylic acids. Examples of the optically active carboxylic acid and the optically active acid halide include (R)-(−)-2-phenylbutyric acid, (1S)-(−)-camphanic acid, and (R)-(+)-α-methoxy-α. -(Trifluoromethyl) phenylacetic acid, (S)-(+)-phenylpropionic acid, and their acid halides, and the like, (1S)-(-)-can because of their availability and ease of separation. It is preferable to use fan acid or its acid halide.
[0010]
The cis-form optically active carboxylic acid ester is obtained by a general method such as an esterification reaction using a catalyst described in Experimental Chemistry Course (4th edition, Volume 22, pages 43 to 46) [issued by Maruzen Co., Ltd.] or a dehydrating agent. From the cis isomer and the optically active carboxylic acid by the esterification reaction used, or by the esterification reaction using the acid halide described in Experimental Chemistry Course (4th edition, Volume 22, pages 50 to 51) [issued by Maruzen Co., Ltd.] And an optically active carboxylic acid halide. Separation of the optically active carboxylic acid ester of (1R, 2R)-(-)-2-tert-butylcyclohexanol from the diastereomer of the obtained cis-optically active carboxylic acid ester, for example, by column chromatography or recrystallization Can be obtained.
[0011]
From the optically active carboxylic acid ester of (1R, 2R)-(−)-2-tert-butylcyclohexanol, the desired (1R, 2R)-(−) — is obtained by hydrolysis of a general ester using an acid or alkali. 2-tert-butylcyclohexanol can be obtained.
[0012]
(1R, 2R)-(−)-2-tert-butylcyclohexanol also represents an optically active carboxylic acid ester of (1R, 2R)-(−)-2-tert-butylcyclohexanol, such as lithium aluminum hydride, It can also be obtained by reducing with a reducing agent such as diisobutylaluminum hydride and hydroborane described in Experimental Chemistry Course (4th edition, Volume 26, page 161) [issued by Maruzen Co., Ltd.].
[0013]
The absolute configuration of (1R, 2R)-(−)-2-tert-butylcyclohexanol obtained as described above is described in, for example, J. et al. Chem. Soc. , (C), 1988 (1966), compared with the optical rotation of (1S, 2S)-(+)-2-tert-butylcyclohexanol.
[0014]
Since (1R, 2R)-(-)-2-tert-butylcyclohexanol has a green odor with a strong fresh feeling, it is used alone or in combination with other components commonly used in fragrance compositions. It can be widely used in products that require perfume, such as perfume, eau de cologne, soap, shampoo, rinse, detergent, cosmetics, spray products, and fragrances.
[0015]
In the case where cis-2-tert-butylcyclohexanol having an optical purity of (1R, 2R)-(−)-2-tert-butylcyclohexanol exceeding 0% ee is blended in the fragrance composition, the blending amount thereof Varies depending on the target blended fragrance, target fragrance, etc., and is not particularly limited as long as the target fragrance can be imparted, but generally 0.1 to 50% by weight in the fragrance composition, preferably 1 to 30% by weight.
[0016]
Furthermore, in the fragrance composition of the present invention, (1R, 2R)-(−)-2-tert-butylcyclohexanol has a trans purity of cis-2-tert-butylcyclohexanol having an optical purity exceeding 0% ee. The (1S, 2R) form or (1R, 2S) form of 2-tert-butylcyclohexanol, which is a form, can also be used as a mixture.
[0017]

Comparative Example 1
In the same manner as in Example 1, from (1S)-(−)-camphanic acid ester of (1S, 2S)-(+)-2-tert-butylcyclohexanol, (1S, 2S)-(+)-2 -Tert-Butylcyclohexanol (rotation [α] D 25 = + 30.5 degrees in chloroform) was obtained. However, the optical purity in the analysis by gas chromatography using an optically active column was 100% ee (retention time 16.50 minutes).
[0024]
Although the fragrance of Comparative Example 1 had a camphor-like herbal fragrance, it had only a weak green fragrance compared to the (1R, 2R) body. The threshold was 80 mg / L, and a concentration twice that of the (1R, 2R) body was required to recognize the aroma.
[0025]
Example 2 and Comparative Example 2
Using the (1R, 2R)-(−)-2-tert-butylcyclohexanol produced in Example 1, a green floral soap perfume was prepared according to the formulation shown in Table 2. Similarly, as Comparative Example 2, a fragrance composition containing cis-2-tert-butylcyclohexanol as a racemate was prepared. When the obtained composition was evaluated for palatability by five professional panelists, Example 2 using the (1R, 2R) body was more similar to the floral note than Comparative Example 2 using the racemic body. The evaluation result that the green feeling which is very well harmonized and reminiscent of a more natural and clean impression is enhanced is preferable.
