Abstract
式(I)的化合物,其中:n=0、1、2、3,且R=C2-C6直链和支链烷基、烯基和环烷基取代基。式(I)的化合物是具有药草香-青香香调的令人感兴趣的香精或香料成分。
Description
本发明涉及能够发出药草香-青香气味的香料和香精成分。
已知香料和香精成分属于药草香-青香家族。一些商购的药草香-青香成分的实例包括WO2004048336中公开的顺式-3-己烯醇、古蓬香胶、吡嗪类、紫苏醛和一些吡啶类。
然而,喹啉类不被视为一类可以提供属于药草香-青香家族的气味或香味的分子。例如,2-异丁基喹啉具有薄荷、壤香、木香气味,而吡拉龙具有壤香、皮革、木香、类似烟草的气味。这些材料都是全芳香喹啉类。
文献中已经公开了5,6,7,8-四氢喹啉衍生物。一些5,6,7,8-四氢喹啉衍生物公开在Monatshefte fuer Chemie 1984,115,1219;J.ChemSoc.Perkin Tr.1,1980,1933)中,然而,未进行其气味描述。
已经公开了其他5,6,7,8-四氢喹啉衍生物(结构如下),但就每个化合物而言,同样未报道气味描述。
另一方面,DE2437901确实描述了三-取代的四氢喹啉的气味。更具体地,该文献描述了作为具有明显辛香、轻微似琥珀的气味的2,5-二甲基-8-异丙基-5,6,7,8-四氢喹啉,即十分不同于药草香-青香成分的特征。
对提供新的同样能够添加到香料制造商和调香师的调配板上的香精和香料成分仍然存在需求,所述香精和香料成分可以对它们所施加的产品赋予药草香-青香香调。
其中
n=0、1、2、3,且
R=C2-C6直链和支链烷基、烯基和环烷基取代基,条件是在清鲜、绿色番茄叶、人参和橙叶气味方面具有极为理想的气味特性,使得这些材料明显适合于在香料和香精工业中应用。
申请人已经研究了其他取代的5,6,7,8-四氢喹啉化合物的愉快感觉。特别地,发现在8-位上被甲基取代的那些材料被发现具有相当令人不愉快的使人联想起甲基吡啶的化学气味,极不期望的强烈薄荷香型。类似地,发现8,8-二取代的衍生物因该原因而成为极弱的增香剂并且不理想。此外,在2-位上被甲基取代的那些材料显示极弱和令人不感兴趣的气味。
因此,本发明在第一个方面中提供了式(I)的化合物作为香精或香料成分的用途。
如上所述,落在式(I)范围内的一些化合物是已知的,但其气味始终未得到描述。
其中:
n=0、1、2、3,且
R=C2-C6直链和支链烷基、烯基和环烷基取代基,
条件是从式(I)的范围内排除以下化合物:
优选的式(I)的化合物是:
8-仲-丁基-5,6,7,8-四氢喹啉、
8-(戊-2-基)-5,6,7,8-四氢喹啉、
8-(戊-3-基)-5,6,7,8-四氢喹啉、
7-仲-丁基-6,7-二氢-5H-环戊二烯并[b]吡啶、
7-(戊-2-基)-6,7-二氢-5H-环戊二烯并[b]吡啶、
7-(戊-3-基)-6,7-二氢-5H-环戊二烯并[b]吡啶、
7-(3-甲基丁-2-烯基)-6,7-二氢-5H-环戊二烯并[b]吡啶。
可以通过根据方案1使商购原料5,6,7,8-四氢喹啉,6,7-二氢-5H-环戊二烯并[b]吡啶类)或6,7,8,9-四氢-5H-环庚三烯并[b]吡啶烷基化来制备式(I)的化合物。
方案1
得到式(I)的具体化合物的合成途径的进一步描述如下文实施例中所述。
由于其理想的气味特性,所以式(I)的化合物适合于用作所有香料应用方式中的香料成分。类似地,其气味也可以在食品、饮料和口腔护理产品中加入芳香气味,使得它们适合于用作香精成分。
因此,在本发明的另一个方面中,提供了赋予、增强、改善或改变加香组合物或加香制品或香精组合物或调味制品愉快特性的方法,该方法包括向所述组合物或制品中添加式(I)的化合物。
由于式(I)化合物的令人意外的特性,所以本发明在其另一个方面中提供了包含式(I)的化合物的香料或香精组合物或调味或加香制品。
所述香料或香精组合物还可以包含式(I)化合物的载体材料、香味或调味基质和其他用于香料或香精配方的佐剂。
本文所用的术语“载体材料”是指从香料或香精观点来看是中性或实际上是中性的材料,即该材料不会显著地改变加香或调味成分的器官感觉特性。
作为载体材料,可以举出的有乳化系统,即溶剂和表面活性剂系统,或常用于香料或香精用品的溶剂。常用于香料或香精工业的溶剂的性质和类型的描述不能穷尽。然而,可以引述用于香料的溶剂的非限制性实例为一缩二丙二醇、邻苯二甲酸二乙酯、肉豆蔻酸异丙酯、苯甲酸苄酯、2-(2-乙氧基乙氧基)-1-乙醇或柠檬酸乙酯。

本文所用的术语“香料或香精基质”是指包含至少一种非式(I)的化合物的香料或香精共同成分的组合物。
此外,所述的共同成分用于赋予令人愉快的作用。例如,如果这种共同成分被视为加香共同成分,则它必须被本领域技术人员视为能够以肯定或令人愉快的方式赋予或改变组合物的气味,而且不仅仅是具有气味。类似地,如果所述的共同成分是香精,则本领域技术人员将其视为能够产生、改变或增强香精的谐香。
存在于基质中的香料或香精共同成分的性质和类型在本文中无法确保更详细地描述,在任何情况下都不可能穷尽,本领域技术人员能够基于其一般知识并且根据预期的应用或用品和期望的器官感觉效应选择它们。
一般地说,加香共同成分属于化学类型,不同类型为醇类、醛类、酮类、酯类、醚类、乙酸酯类、腈类、萜烯烃类、含氮或含硫杂环化合物和精油,且所述加香共同成分可以具有天然或合成来源。在任何情况下,许多这些共同成分可以在参考书中举出,例如教科书S.Arctander,Perfume and Flavor Chemicals,1969,Montclair,NewJersey,USA,或其更新的版本或其他类型性质的著作以及香料领域中的大量专利文献。还应理解,所述共同成分还可以是已知以受控方式释放各种类型的加香化合物的化合物。

香精共同成分可以包括醛类和酯类,例如,可以使用乙酸肉桂酯、肉桂醛、柠檬醛二乙缩醛、乙酸二氢葛缕酯、丁子香酚49甲酸酯、对-甲基茴香醇等。醛香料的另外的实例包括乙醛(苹果)、苯甲醛(樱桃,杏仁)、茴香醛(甘草,大茴香)、肉桂醛(肉桂)、柠檬醛即α-柠檬醛(柠檬,白柠檬)、橙花醛即β-柠檬醛(柠檬,白柠檬)、癸醛(橙,柠檬)、乙基香草醛(香子兰,奶油)、天芥菜即胡椒醛(香子兰,奶油)、香草醛(香子兰,奶油)、α-戊基肉桂醛(辛香水果香精)、丁醛(黄油,干酪)、戊醛(黄油,干酪)、香茅醛(修饰物,许多类型)、癸醛(柑橘类水果)、醛C-8(柑橘类水果)、醛C-9(柑橘类水果)、醛C-12(柑橘类水果)、2-乙基丁醛(浆果类)、己烯醛即反式-2(浆果类)、甲苯基醛(樱桃,杏仁)、藜芦醛(香子兰)、2,6-二甲基-5-庚烯醛即甜瓜醛(甜瓜)、2,6-二甲基辛醛(绿色果实)和2-十二碳烯醛(柑橘,橘子)等。一般而言,可以使用任意的调味剂或食品添加剂,例如描述在Chemicals Usedin Food Processing,出版物1274,63-258页,National Academy ofSciences中的那些。将该出版物引入本文参考。
本文所用的术语“佐剂”是指影响组合物的非愉快性能的成分。例如,佐剂可以是起辅助加工组合物或包含组合物的制品的作用的成分,或它可以改善所述组合物或制品的操作或贮存。它还可以是提供另外的有益性的成分,例如给组合物或制品赋予颜色或质地。它还可以是给组合物或制品中一种或多种成分赋予耐光性或化学稳定性的成分。常用于香料和香精组合物的佐剂的性质和类型的详细描述不能穷尽,但必须要提及所述成分对本领域技术人员而言是众所周知的。佐剂的实例包括溶剂和共溶剂、表面活性剂和乳化剂、粘度和流变性调节剂、增稠剂和胶凝剂、防腐剂材料、颜料、染料和着色物质、增充剂、填充剂和增强剂、针对热和光的有害作用的稳定剂、疏松剂、酸化剂、缓冲剂和抗氧化剂。
此外,式(I)的化合物可以用于现代香料和香精技术领域以积极地赋予或改变加入所述化合物(I)的组合物或制品的气味。因此,包含至少一种通式化合物的加香或调味的制品构成了本发明的另一个方面。
所述制品的成分的性质和类型在本文中不进行更详细描述,在任何情况下,其都不可能是穷尽的,本领域技术人员能够基于其一般知识并且根据所述产品的性质和期望的效果选择它们。
适合的制品的实例包括:消费品,其可以包括固体或液体洗涤剂和织物柔软剂以及所有其他香料中常用的制品,即香水、古龙香水或剃须后洗剂、香皂、淋浴盐、摩丝、油或凝胶、卫生用品或护发产品例如香波、身体护理产品、除臭剂或止汗剂、空气清新剂,且还有化妆品。作为指定用品的洗涤剂,例如洗涤剂组合物或清洁产品,它们用于洗涤或清洁各种表面,例如预以用于织物、盘子或硬表面处理,无论是将它们用于家用还是工业化应用。其他加香制品是织物清洁剂、熨平水、纸张、擦拭物或漂白剂。
消费品还可以包括任意固体或液体组合物,消费所述消费品是为了至少一种营养和愉悦感,或预以保留在口腔中一定时间期限,然后弃去。宽泛的一般清单包括、但不限于所有类型的食品、糖食、烘烤制品、糖果点心、乳制品和饮料以及口腔护理产品。
一些上述举出的消费品的基质可以代表式(I)的化合物的侵蚀性介质,使得有必要防止后者发生过早的分解,例如通过包囊。
可以掺入不同的上述举出的制品或组合物的式(I)的化合物的比例可以在宽数值范围内改变。这些数值依赖于所加香的制品的性质和期望的器官感觉效应以及当将本发明的化合物与本领域常用的加香或调味共同成分、溶剂或添加剂混合时指定基质中的共同成分的性质。
例如,就香料组合物而言,式(I)的化合物的典型浓度约占掺入它们的组合物重量的0.01%-3%重量,乃至更高。当将这些化合物掺入加香制品时,可以使用低于它们的浓度,例如约为0.0001%-0.5%重量。
就香精组合物而言,式(I)的化合物的典型浓度约占掺入它们的组合物重量的0.01%-3%重量,乃至更高。当将这些化合物掺入调味制品时,可以使用低于它们的浓度,例如约为0.0001%-0.05%重量。
