Described are a series of compounds defined according to structure:
wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein Z is in the alternative one of the moieties:
wherein R1, R2, R3, R4, R5. R6 and R7 are each inthe alternative hydrogen or methyl; wherein R8 and R9 are in the alternative the same or different and are hydrogen orC1-C4 alkyl; with the proviso that one of R1, R2, R5, R6 or R7 is methyl and the other of R1, R2, R5, R6 and R7 is hydrogen; and with the additional proviso that R3 and R4 are not both methyl and uses thereof for augmenting or enhancing the organoleptic properties of consumable materials including foodstuffs, chewing gums, toothpastes, medicinal products, smoking tobaccos, chewing tobaccos, perfumes, perfumed articles, colognes, smoking tobaccos or smoking tobacco articles, as well as catalytic and thermal processes for preparing such compounds by means of Diels-alder reactions between arcylic compounds and monomethyl substituted cyclopentadienes or mixtures thereof.
所描述的是根据结构定义的一系列化合物:
其中,虚线代表碳碳单键或碳碳双键;其中,Z 是其中的一个分子:
其中 R1、R2、R3、R4、R5.R6和R7各自是氢或甲基;其中R8和R9是相同或不同的,并且是氢或C1-C4烷基;但R1、R2、R5、R6或R7中的一个是甲基,R1、R2、R5、R6和R7中的另一个是氢;另外,R3 和 R4 并非都是甲基,其用途是增加或提高消费品的感官特性,包括食品、口香糖、牙膏、医药产品、烟草、咀嚼烟草、香水、以及通过芳香族化合物与单甲基取代环戊二烯或其混合物之间的 Diels-alder 反应制备此类化合物的催化和热工艺。
