Abstract

Disclosed is a method for the preparation of formyltetrahydropyrans (I) by dehydrogenating hydroxymethyltetrahydropy-rans (II) in the presence of a copper, silver and/or gold catalyst. The formyltetrahydropyrans (I) thus obtained are useful interme-diates in the preparation of pharmaceuticals and phytopathalogical products.
