    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a 5-alkoxy-substituted oxazole and a method for producing a pyridoxine derivative. SOLUTION: The 5-alkoxy-substituted oxazole is obtained by converting an α-isocyano alkylic acid ester in the presence of a base at >80°C and separating the 5-alkoxy-substituted oxazole from the reaction mixture simultaneously with the converting reaction, and the pyridoxine derivative is obtained by converting an amino acid into an amino acid ester, converting the obtained into a formamido acid ester, converting the obtained into an α-isocyanoalkyl acid ester, converting the obtained into a 5-alkoxy-substituted oxazole in the presence of a base at >80°C and separating the 5-alkoxy-substituted oxazole from the reaction mixture simultaneously with the converting reaction, reacting the obtained 5-alkoxy-substituted oxazole with a protective diol to obtain an Diels-Alder adduct and treating the obtained with an acid and removing the protective group to convert into the pyridoxine derivative.

    Abstract: A heterogeneous ruthenium catalyst comprises an amorphous silicium dioxide in the form of a support material and is produced by one or several impregnations of the support material with a rhenium salt solution, drying and reduction. Said invention is characterised in that the silicium dioxide support material has a BET surface (according to DIN 66131) ranging from 250 ti 440 m 2 /g, a pore volume (according to DIN 66134) ranging from 0.7 to 1.1 ml/g and a pore diameter (according to DIN 66131) ranging from 6 to 12 nm. The invention also relates to a method for producing a carboxylic aromatic group, in particular a method for producing bisglycidyl ethers of formula (I), wherein R is CH 3 or H, by hydrogenating the core of an aromatic bisglycidyl ether of formula (II) in which the heterogeneous ruthenium catalyst is introduced.
