Odor properties of some tetrahydropyranyl ethers.

Several tetrahydropyranyl derivatives of phenols and alcohols have been prepared with the aim of reproducing the floral note of hydroxycitronellal in compounds of easier and cheaper synthesis. Some of the derivatives, particularly those prepared from cis-4-methylcyclohexanola nd p-alkylphenols, present a pleasant floral character as the main note and could be used as detergent additives and in other products of pH above neutrality. This research also represents a contribution toward the understanding of the relationships between molecular structure and the odor of muguet
