【産業上の利用分野】本発明は一般式(1)
(1)
(式中、波線は二重結合のシス体および/またはトランス体を示す)で表される3−(3−へキセニル)−2−シクロペンテノンからなる香料素材、および該香料素材を有効成分として含有する香料組成物に関する。また、上記化合物を用いた賦香方法に関する。
【0002】
【従来の技術】
近年、各種香粧品類、保健衛生材料等の多様化に伴い、これらの賦香(匂い付け)に用いる香料においては、従来にない新しい要望が高まり、嗜好性の高いユニークな香気であること、化学的に安定であること、他に使用する香料との調合性に優れていることなどが要求されている。
従ってそれらを兼ね備えた香料素材を開発する事は香料産業上極めて重要である。
これまでに、3−(3Z−へキセニル)−2−シクロペンテノン(2(Z))は、例えば8Z−ウンデカン−8−エン−2,5−ジオン(3)のアルドール縮合により、シス−ジャスモン(4)を合成する際の副生成物として知られている(Helv.Chim.Acta.61,990(1978),CH580555(1976))。また、レトロアルドール反応によりシス−ジャスモンを合成する場合の原料としても報告されている(J. Am. Chem. Soc., 93, 5309(1971))。
【0003】
しかしながら、3−(3Z−へキセニル)−2−シクロペンテノン(2(Z))はシス−ジャスモン合成にとっては不要な副生成物であり、また単なる反応原料として認知されるのみで、香料素材として非常に有用である事はこれまで全く知られていなかった。さらに二重結合の異性体である3−(3E−へキセニル)−2−シクロペンテノンに至っては、化合物自体の報告すら見出せなかった。
【0004】
【0005】
【発明が解決しようとする課題】
本発明の目的は、上記の要望を満足する嗜好性が高く優れた香料化合物を提供することにある。また、当該香料化合物を有効成分として含有する香料組成物を提供することにある。
【0006】
【課題を解決するための手段】
本発明者らは前述の要望に応えるべく鋭意研究した結果、次に示す3−(3−へキセニル)−2−シクロペンテノンが嗜好性の高いユニークな香気を有し、他に使用する香料との調和性に優れていることを見出し本発明を完成させた。
【0007】
即ち、本発明は次の一般式(1)
(1)
(式中、波線は二重結合のシス体および/またはトランス体を示す)で表される3−(3−へキセニル)−2−シクロペンテノンからなる香料素材、および該香料素材を有効成分として含有する事を特徴とする香料組成物を提供することにある。
【0008】
【発明の実施の態様】
以下、本発明を詳細に説明する。
本発明の式(1)で示される3−(3−へキセニル)−2−シクロペンテノンは、側鎖がトランス体の3−(3E−へキセニル)−2−シクロペンテノン単独、側鎖がシス体の3−(3Z−へキセニル)−2−シクロペンテノン単独あるいはこれらの混合物を意味する。これら化合物あるいは混合物は優れた香りを有し香料として有効である。とくに、側鎖がシス体の3−(3Z−へキセニル)−2−シクロペンテノンは優れた香りを有し、香料として有効である。
すなわち上記化合物はいずれもグリーン、フローラル、シトラス、ファッティ−、ニトリル様な特有の香気を有するが、トランス体はよりグリーン感が強く、またシス体はよりフルーティ−感が強い。
さらに本発明化合物である3−(3−へキセニル)−2−シクロペンテノンを通常使用されている香料成分と混合し香料組成物を調製することで、その香料組成物にボリューム感のあるナチュラルでインパクトのあるボディーノートを付与でき、「質感」のある香りをもたらす極めて有用な高級香料であるということができる。
【0009】
本発明の式(1)で示される3−(3E−へキセニル)−2−シクロペンテノンは、文献未記載の化合物である。この化合物は、例えばつぎの方法により製造できる。すなわち、2−メチルフランとアクロレインから合成したフラニルアルデヒドのシス選択的Wittg反応によるシス−ジャスモンの合成ルートにおいて(J. Chem. Soc., C, 1024(1969))、文献記載(Angew. Chem. Int. Ed. Engl., 5, 126(1966))のトランス選択的Wittig反応条件を適用することで相当するトランス体を得る。このものをシス体合成と同様な条件下、酸性加水分解および塩基性アルドール縮合により環化させ、相当するトランス−ジャスモンおよび3−(3E−へキセニル)−2−シクロペンテノンの混合物を得る。その後のシリカゲルカラムクロマトグラフィー分離により、目的の3−(3E−へキセニル)−2−シクロペンテノンを分離し、調製することができる。
【0010】
また3−(3Z−へキセニル)−2−シクロペンテノンの製造法は特に限定されるものでは無いが、前述したシス−ジャスモン合成時に副生成物として数%得られる以外にも、以下の報告された方法によって製造する事ができる。
例えばシクロペンテノンに3Z−へキセニルリチウムを1,2付加させた後、アリル転移を経由して酸化することで合成するルートが報告されている(J. Org. Chem., 39, 2317(1874))。
【0011】
3−(3Z−へキセニル)−2−シクロペンテノン及び3−(3E−へキセニル)−2−シクロペンテノンの混合物は両者をそれぞれ調製した後、任意の量割合にて混合することにより得られる。
