A Simple Synthesis of 9-Ketodihydro-α-damascone

The compounds, 9-keto-8,9-dihydro-damascones or damascenones, are used as the ingredients in the production of perfumes and aromas. Since these compounds are able to be converted into damascones and damascenones. 9-keto-8,9-dihydro-α-damascone [2,6,6 -trimethyl-1-(1,3-dioxobutyl)cyclohex-2-ene] (I) may be considered as a precursor of α-damascone. Until now, (I) and its analogues were synthesized by the multistep reactions.

A Mathematical Model for Odors Applied to Binary Odor Mixtures

This expanded mathematical model is a modification of Berglund’s model (1973).1 The modification explains the elimination of one odor by another, the synergy of odors of low intensity and the existence of odorless substances, which have deodorant properties.

Fragrance intensity measurement by magnitude estimation

Psychologist's Corner. During the past 25 years a new form of sensory evaluation--magnitude estimation--has become very popular among research scientists in a number of different fields. The premise and forte of magnitude estimation is that people are able to assess sensory intensity by numerical means. Furthermore, the magnitude estimation method allows the participant an opportunity to use a wide range of numbers, with the property that ratios or proportions among the numerical assignments reflect ratios of sensory intensities.

Spectroscopic characterisation of a rare monoterpene from Blumea Mollis

Beginning with earlier studies on the essential oil separated from different species of Blumea, this material has been the subject of many chemical and biological investigations. Chemical investigations of the oils of different Blumea species have afforded different terpenoids. Thus the oil of Blumea eriantha has a major constituent, d-carvotanacetone; oil of Blumea lacera contains the cineol, d-fenchone and citral; oil of Blumea malcolmii yielded d-carvotanacetone and 1-tetrahydrocarvone; and the oil of Blumea membranceae contains 1,4-(8)-p-methadiene; δ-cadinene; 2,3-dimethoxy-p-cymene; 1,2-dimethyl-3-isopropenyl cyclopent-1-en-4-one; 5-hydroxy-p-cymene-2-oxybornylene; 2-methyl-5-isopropyl cyclopent-1-one carbonylic acid methyl ester; and citronellyl acetate. But this monoterpene has not been reported yet.
