Abstract: 4-Formyltetrahydropyrans of the general formula I (I) where R1 is hydrogen, C1-C12-alkyl, C2-C12-alkenyl, C1-C6-alkoxy-substituted C1-C12-alkyl, C4-C12-cycloalkyl, unsubstituted or substituted aryl, hetaryl or aralkyl, or an unsubstituted or substituted, saturated or unsaturated 5-membered or 6-membered ring which may be interrupted by N, O or S, are prepared by a process in which a pyran derivative of the general formula II (II) where R1 is as defined above, R2 and R3 are each OH or together are an oxygen atom and thus form an oxirane ring, and R4 is hydrogen where R2 and R3 are each OH, and is hydrogen or tert-butoxycarbonyl where R2 and R3 together are an oxygen atom, is treated at elevated temperatures with a catalyst selected from the group consisting of zeolites, phosphates, boric acid on a carrier and silica or mixtures of these. Novel 4-formyltetrahydropyrans are also proposed.

Abstract: Method for the preparation of 4-hydroxymethyltetrahydropyrans of the general formula I in which R , R , R and R denote hydrogen, C1- to C12-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C20-aralkyl, by reacting tetrahydropyrancarboxylic esters of the general formula II in which R1, R2, R3 and R4 have the abovementioned meanings and R5 denotes hydrogen or C1- to C12-alkyl, at temperatures of 50 to 400 DEG C and pressures of 1 to 400 bar in the presence of hydrogen and hydrogenation catalysts.

Abstract: Disclosed is a method for the preparation of formyltetrahydropyrans (I) by dehydrogenating hydroxymethyltetrahydropyrans (II) in the presence of a copper, silver and/or gold catalyst. The formyltetrahydropyrans (I) thus obtained are useful intermediates in the preparation of pharmaceuticals and phytopathalogical products.
