摘要: 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.

摘要: Alcohols are prepared by electrochemical reductive coupling of an aromatic vinyl compound and a carbonyl compound in a process which comprises electrolyzing an electrolyte solution in an electrochemical cell, the electrolyte solution comprising the aromatic vinyl compound, the carbonyl compound and a non-aqueous protic solvent, such as methanol, wherein the electrolyte solution is in contact with a carbon-based cathode. Styrene is reacted with acetone to prepare 2-methyl-4-phenyl-2-butanol.

摘要: The present invention relates to a process for the preparation of 2-substituted 4-hydroxy-4-methyltetrahydropyrans by reacting 3-methylbut-3-en-1-ol (isoprenol) with the corresponding alkenealdehydes in the presence of a strongly acidic ion exchanger with subsequent hydrogenation. Specifically, the present invention relates to a corresponding process for the preparation of 2-isobutyl-4-hydroxy-4-methyltetrahydropyran by reacting isoprenol with prenal, with subsequent hydrogenation.
