Abstract:
The present invention relates to aroma chemical compositions containing 3,5-diethyl-2-propyl-tetrahydropyran, a 3,5-diethyl-2-propyl-dihydropyran or a 3,5-diethyl-2-propyl-pyran, a mixture of such compounds, a stereoisomer of one of these compounds, or a mixture of stereoisomers of one or more of these compounds. The invention further relates to a method for preparing such compounds, stereoisomers or mixtures thereof, to the composition obtainable by this method, to the use of such compounds as an aroma chemical or for modifying the scent character of a fragranced composition; and to a method for preparing a fragranced composition or for modifying the scent character of a fragranced composition using said compounds. Moreover, the invention relates to 3,5-diethyl-2-propyl-tetrahydropyran, to its stereoisomers and to mixtures of these stereoisomers.
