Abstract:
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.
