1. Field of the Invention
The present invention relates to cyclohexanol derivatives and fragrance compositions containing the same.
2. Description of the Prior Art
It is known that hydrogenated catecholcamphene adducts obtained by the hydrogenation of an adduct of camphene with catechol have a sandal odor. (Japan Patent Application Laid-Open No. 106,853/1977 and No. 118,507/1982). It is also known that condensation of 2-ethylidene-5-norbornene ("EBH") with phenol in the presence of a cation exchange resin gives a 1:1 condensation product. (Chemical Abstracts, Vol. 84, 30579x (1974); Neft. Gaz, page 128 (1974)).
While fragrant substances are known which have a green-floral type odor, many of the fragrance materials belonging to the green-floral odor type have an aldehyde group as a functional group. (Perfumer and Florist, 5 (6), 1 (1980) and ibid., 6 (1), 1 (1981)). Unfortunately, the aldehyde group is known to be easily oxidizable and notoriously susceptible to attack by acids and alkalis. Hence, fragrant substances bearing an aldehyde group tend to be chemically labile or unstable.
Additionally, many of the fragrant substances having a green-floral type odor have a relatively simple chemical structure and, hence, a low molecular weight, which results in the non-persistence of the odor. Hence, a need continues to exist for a fragrant substance or fragrance composition which has a green-floral type odor and which is chemically stable. Moreover, a need also continues to exist for such compositions or substances whose green-floral type odor is persistent.
