The invention relates to a method for producing tetrahydropyrane derivatives which comprise at least one additional ring containing oxygen. The invention also relates to, in particular, compounds having two tetrahydropyrane rings or at least one tetrahydropyrane ring and a dioxane ring. Said methods use condensation comprising aldehydes and/or ring-closing reactions. The inventive production methods enable novel tetrahydropyrane-compounds having at least two O-heterocyclic rings to be obtained. |
