Oxygen containing macrocyclic compounds of formula ##STR1## wherein (a) the dotted lines indicate the location of an endocyclic single or double bond in positions 4 and 8 of the ring and of an exocyclic carbon-oxygen single bond in position 1, the wavy lines define a C--C bond of E or Z configuration when the bond in positions 4 and 8 is a double bond, and the symbols Z.sup.1 and Z.sup.2, taken together, define a cyclic acetal or ketal group represented by the formula ##STR2## wherein the symbols R.sup.1 and R.sup.2, identical or different, represent each an alkyl radical, linear or branched, containing from 1 to 6 carbon atoms, or one of said symbols represents a hydrogen atom and the other an alkyl radical defined as above; or wherein (b) the symbol Z.sup.1 stands for an oxygen atom or an OH group, the dotted lines indicate the location of an endocyclic single or double bond in positions 4 and 8 of the ring and of an exocyclic carbon-oxygen single (Z.sup.1 .dbd.OH) or double (Z.sup.1 .dbd.O) bond in position 1, the wavy lines define a C--C bond of E or Z configuration when the bond in positions 4 and 8 is a double bond, and the symbol Z.sup.2 stands for a group OR.sup.3, wherein R.sup.3 represents a linear or branched alkyl radical, containing from 1 to 6 carbon atoms, are novel compounds which have useful odor properties. They can be used as active ingredients in perfuming compositions are perfumed products, to which they confer spicy-aldehydic type odor notes. A process for the preparation of the compounds of formula (I) is also disclosed.
公式为 ##STR1## 的含氧大环化合物,其中:(a)虚线表示环中4和8位置的内环单键或双键和位置1的外环碳-氧单键;波浪线定义了当4和8位置的键为双键时的E或Z构型的C-C键,符号Z.sup.1和Z.sup.2一起定义了由公式 ##STR2## 表示的环状缩醛或缩酮基团;其中符号R.sup.1和R.sup.2相同或不同,分别表示含有1至6个碳原子的直链或支链烷基基团,或其中一个表示氢原子,另一个表示如上定义的烷基基团;或者(b)符号Z.sup.1表示氧原子或OH基团,虚线表示环中4和8位置的内环单键或双键和位置1的外环碳-氧单(Z.sup.1 .dbd.OH)或双(Z.sup.1 .dbd.O)键;波浪线定义了当4和8位置的键为双键时的E或Z构型的C-C键,符号Z.sup.2表示一个OR.sup.3基团,其中R.sup.3表示含有1至6个碳原子的直链或支链烷基基团。这些新化合物具有有用的气味特性,可以用作香料组合物或香料产品中的活性成分,赋予其辛辣醛类气味。还公开了制备公式(I)化合物的方法。
