Abstract: A process for preparing a 1-substituted 5- and/or 3-hydroxypyrazole of the formulae I and II, respectively in which R1 is C1 -C6 -alkyl, C2 -C6 -alkenyl, C2 -C6 -alkynyl, C3 -C6 -cycloalkyl or C1 -C4 -alkoxy. These groups may be substituted by halogen, C1 -C4 -alkoxy, phenoxy, C1 -C6 -alkoxycarbonyl, C1 -C6 -alkylthiocarbonyl or by a cyclic ring system having 3-14 ring atoms. An alkyl vinyl of formula V, reacts with phosgene VIa, "diphosgene" VIb or "triphosgene" VIc, producing an acyl chloride of the formula VII. The alkyl vinyl R2 is C1 -C6 -alkyl or C3 -C6 -cycloalkyl. The acyl chloride is converted by the elimination of hydrogen chloride into 3-alkoxyacryloyl chloride of the formula VIII. Esterifying the 3-alkoxyacryloyl chloride with an alcohol of formula IX, in which R3 is C1 -C6 -alkyl or C3 -C6 -cycloalkyl. This results in the alkyl 3-alkoxyacrylate of the formula III, Reacting the alkyl 3-alkoxyacrylate with a hydrazine of the formula IV, where R1 is defined above a)at a pH of 6-11 to give 5-hydroxypyrazoles of the formula I or b) b) at a pH of 11-14 to give 3-hydroxypyrazoles of the formula II. A 1-substituted 5- and/or 3-hydroxypyrazole of the formulae I and II produced from the above stated process.

Abstract: The invention relates to a method for producing alkyne diols by reacting ketones with acetylenic hydrocarbons in an organic solvent in the presence of a base which contains potassium alcoholates of primary and/or secondary alcohols. The alkyne diols are produced while forming adducts which precipitate out of the reaction mixture and which are comprised of alkyne monoalcohols and/or alkyne diols and a base. The stoichiometries of the reaction partners are selected such that gelatinous adducts are formed which comprise a spherical surface, whereby the reaction mixture remains agitable during the entire reaction.

Abstract: Production of 5-alkoxy oxazoles (I) comprises heating an alkyl alpha -isocyanoalkanoate ester (II) at a temperature above 80 deg C in the presence of an auxiliary agent and simultaneously separating the product from the reaction mixture. Production of 5-alkoxy oxazoles of formula (I) comprises heating an alkyl alpha -isocyanoalkanoate ester of formula (II) at a temperature above 80 deg C in the presence of an auxiliary agent and simultaneously separating the product from the reaction mixture. R1 = optionally substituted 1-6C alkyl; R2 = H or optionally substituted 1-6C alkyl. An Independent claim is also included for a process for producing pyridoxine derivatives of formula (IX), comprising: (1) converting an amino acid of formula (III) to an ester of formula (IV); (2) converting (IV) to a formamido ester of formula (IV); (3) converting (IV) to (II), converting (II) to (I) as above; (4) reacting (I) with a protected diol of formula (VI) to form a Diels-Alder adduct of formula (VII); and (5) converting (VII) to (IX) by acid treatment and deprotection. R3, R4 = protecting groups or together form a protecting group.

Abstract: The invention relates to a method for hydrogenating at least one organic compound by bringing said organic compound into contact with a gas containin g hydrogen in the presence of a catalyst. Said catalyst comprises ruthenium as an active metal, either alone or combined with another metal of the subgroup s I, VII or VIII of the periodic table, deposited on an amorphous silicon dioxide-based support. Said catalyst is obtained by i): treating the amorpho us silicon dioxide-based support with a halogen-free aqueous solution of a low- molecular ruthenium compound, and subsequently drying the treated support at a temperature of less than 200 ~C, ii) reducing the solid matter obtained in i ) with hydrogen at a temperature ranging from 100 to 350 ~C, wherein step ii) is carried out directly after step i).
