METHOD FOR THE PRODUCTION OF TETRAHYDROPYRANOLS SUBSTITUTED IN THE 2-POSITION |
摘要 |
The invention relates to a method for producing 4-hydroxy-4-methyl-tetrahydropyran substituted in the 2-position by reacting 3-methylbut-3-en-1-ol (isoprenol) with the corresponding alkene aldehydes in the presence of a very acidic ion exchanger, followed by hydrogenation. The invention especially relates to a corresponding method for producing 2-isobutyl-hydroxy-4-methyl-tetrahydropyran by reacting isoprenol with prenal, followed by hydrogenation. |
