Description
本发明涉及具有树木、香根和类似广霍香气味特征的新型化合物。此外,本发明涉及其生产方法和含有它们的香料和香味组合物。
在文献中公开了具有树木、香根和类似广霍香气味特征的化合物,例如天然存在于香精油内且可通过水蒸汽蒸馏植物或植物的部分而分离的倍半萜类。该方法的成本非常高且所分离的化合物的质量和气味以及香味特征可随气候和植物来源的变化而变化。因此,在香味和香料工业中继续需要赋予、提高或改进树木、香根和类似广霍香特征的新型化合物。

在另一实施方案中,本发明的化合物可在香料应用中使用,和尤其可用于改性例如草莓和悬钩子香料(也称为褐色香料)。它们可在草本混合物和茶中使用。本发明的化合物也非常适用于例如漱口水应用。
在香料应用中,本发明的化合物可以以香料组合物重量的0.001-5wt%的用量范围,更优选0.01-0.5wt%存在于组合物中。本发明的化合物可用于草本香料组合物、草莓和悬钩子组合物、褐色香料组合物或茶组合物中。
当在香味应用中使用时,本发明的化合物可在宽的用量范围内使用,这取决于特定的应用和其它增味剂成分的本性和用量,可以是例如约0.001-约20wt%。在一个实施方案中,可在织物软化剂中使用该化合物,其用量为约0.001-0.05wt%。在另一实施方案中,可在醇溶液中使用本发明的化合物,其用量为约0.1-20wt%,更优选约0.1至5wt%。
然而,这些数值不应当限制本发明,这是因为有经验的香味工作者和香料专家,在采用较低或较高浓度下,也可实现这些效果或可能产生新的调和。
也可通过直接混合香味组合物与香味应用,在香味应用中使用本发明的化合物,或者可在前期步骤中,用捕获材料,例如聚合物、胶囊、微胶囊和纳米胶囊、脂质体、成膜剂、吸收剂如碳或沸石,环状寡糖及其混合物来捕获它们,或者可将它们化学键合到当施加外部刺激如光、酶或类似物时用于释放香味分子的基材上,然后与该应用混合。
因此,本发明另外提供制造香味应用的方法,该方法包括使用常规的技术与方法,或者通过直接混合结构式I的化合物到应用中或者通过混合含结构式I的化合物的香味组合物,然后将所述香味组合物混合到香味应用中,从而掺入结构式I的化合物作为香味成分。
此处所使用的“香味应用”是指含增味剂的任何产品,如精细香料,例如香料和化妆水(Eau de Toilette);家用产品,例如洗碗机用洗涤剂、表面清洗剂;洗涤产品,例如软化剂、漂白剂、洗涤剂;身体护理产品,例如香波、淋浴凝胶;和化妆品,例如除味剂、雪花膏。通过例举方式给出该产品清单且无论如何不认为是限制。
可根据下述方法制备本发明的化合物,其中在本领域技术人员公知的反应条件下,使合适地取代的环己酮与烯丙基溴或烯丙基氯反应(Bull.Chem.Soc.Jpn.,2298-2303(1993))。在二氯化乙基铝或二氯化甲基铝存在下,所得烷基化环己酮(以下所示的结构式II)可发生转化,结果提供其中R12和R13一起代表氧原子的结构式I的化合物,正如流程1的结构式Ia、Ib和Ic的化合物所示。例如Snider等在Journal ofAm.Chem.Soc.1980,102,5872-5880中公开了其中这种路易斯酸催化的反应可在其下进行的条件,在此引入其作为参考。
在C1处的所得羰基可被还原和/或烷基化,得到结构式I的进一步的化合物。类似地,若在C6和C8处存在双键,则可以以已知的方式还原它,得到结构式I的更进一步的化合物。
流程1:
也可通过使酚与金属氢化物和链烯基氯反应,使合适地取代的酚类发生烷基化作用(Greuter,H.等(1997)Helv.Chim.Acta,60,1701),接着氢化来制备结构式II的化合物。
是否形成结构式Ia、Ib、Ic的化合物或其混合物取决于烷基化环己酮(II)的取代基结构R2、R3和R16。若结构式II的R2、R3和R16为氢,则形成结构式Ic的化合物作为主要产品。若结构式II中的R2和R3同时不为氢,则形成结构式Ia和Ib的化合物的混合物作为主要产品。若结构式II中的R2和R3为氢且结构式II中的R16不为氢,则形成结构式Ia和Ic的化合物的混合物作为主要产品。这些化合物可作为混合物用于香料和/或香味组合物中,然而,人们希望使用纯形式的化合物,可根据本领域已知的方法,通过纯化工艺,如HPLC或制备型GC,容易地分离它们。
此处所使用的术语“主要产品”是指含至少50wt%,更优选大于75wt%,最优选大于90wt%该化合物的产品。当该术语与化合物的混合物,例如结构式Ia的一种化合物和结构式Ic的一种化合物关联使用时,它指含至少50wt%,更特别地大于75wt%,最特别地大于90wt%该混合物的产品。
也可通过光化学引发进行结构式II化合物的转化,用于选择制备结构式Ia的化合物。令人惊奇地,我们已发现,可通过结构式II化合物的光化学引发的分子内[2+2]环加成,形成结构式Ia的化合物。对于光化学引发来说,可使用汞灯约1-15小时时间段。然而,引发时间可能取决于所使用的溶剂和取决于添加剂如敏化剂和路易斯酸。优选的溶剂是甲醇、乙醇和异丙醇。
因此,本发明另一方面涉及通过光化学引发的环加成制备结构式Ia化合物的方法。
在实施例中提供了关于反应条件的进一步的细节。
