Feb 26, 2021 · In this review, the synthesis of damascones and damascenones will be classified according to the starting cyclic substrates (ionone, cyclocitral, cyclogeranate and cyclohexenyl methylketones) and subdivided according to the starting materials used to …

Damascones are a series of closely related chemical compounds that are components of a variety of essential oils.

In some embodiments, the composition comprises dodecyl thio-damascone. Such freshening compositions may be used to prolong perfume release, while reducing malodors on inanimate surfaces or in...

Feb 26, 2021 · The stable isotope dilution assay (SIDA) is one of the most precise analytical methods based on using isotopically labelled standards. Herein, we describe the synthesis of d 6-β-damascenone, d 6-β-damascone, and d 6-safranal, other aroma compounds in nature, starting from the readily available deuterated starting material d 6-acetone.

Freshening compositions comprising a perfume material and a Sulfur-containing pro-perfume; and methods thereof are provided. In some embodiments, the composition comprises dodecylthio-damascone. Such freshening compositions may be used to prolong perfume release, while reducing malodors . on inanimate Surfaces or in the air.

In some embodiments, the composition comprises dodecyl thio-damascone. Such freshening compositions may be used to prolong perfume release, while reducing malodors on inanimate surfaces or in the air.

In this work, we describe a study on the biotransformation of seven natural occurring apocarotenoids by means of eleven selected fungal species. The substrates, namely ionone (α-, β- and γ-isomers), 3,4-dehydroionone, damascone (α- and β-isomers) and theaspirane are relevant flavour and fragrances components.
