    • Described are alkyl-substituted tetra- or hexahydrobenzopyran derivatives defined according to one of the generic structures: ##STR1## wherein Z is a moiety in the alternative either ##STR2## wherein in the moiety having the structure: ##STR3## R' is methyl or ethyl and in the moiety having the structure: ##STR4## one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines represent carbon-carbon single bonds; wherein R.sub.1 and R.sub.2 taken separately represent hydrogen or C.sub.1 -C.sub.3 lower alkyl (with the proviso that R.sub.1 and R.sub.2 are not both hydrogen) or R.sub.1 and R.sub.2 taken together complete a C.sub.5 or C.sub.6 cycloalkyl moiety; and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles including but not limited to solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, hair preparations, cosmetic powders and perfumed polymers. Also described are synthesis processes for preparing such alkyl-substituted tetra- or hexahydrobenzopyran derivatives by means of reacting isopulegol or an isomer thereof with an acetal or ketal.
    • 描述了根据以下通用结构之一定义的烷基取代的四或六氢苯并吡喃衍生物:其中Z是可选择的部分或其中的“IMAGE”或“IMAGE”,其中在具有以下结构的部分中: R'是甲基或乙基,并且在具有以下结构的部分中:虚线之一是碳 - 碳双键,虚线中的每一个代表碳 - 碳单键; 其中R1和R2分别代表氢或C1-C3低级烷基(前提是R1和R2不同时为氢)或R1和R2一起形成C5或C6环烷基部分; 包括但不限于固体或液体阴离子,阳离子,非离子或两性离子洗涤剂,织物柔软剂组合物,织物柔软剂制品,毛发制品,化妆粉和加香聚合物的香料组合物,古龙水和香料制品的香气。 。 还描述了通过异丙醇或其异构体与缩醛或缩酮反应制备这种烷基取代的四或六氢苯并吡喃衍生物的合成方法。
