    Abstract: The invention relates to a method for producing substituted hydroxypyrazoles and new intermediate products. It relates in particular to a method for producing compounds of formula (I) in which R1 is hydrogen, an aliphatic group with between 1 and 8 carbon atoms, C¿1?-C6-alkoxycarbonyl, C1-C6-alkyl thiocarbonyl or a cyclic ring system with between 3 and 14 ring atoms; R?2¿ is hydrogen, an aliphatic group with between 1 and 8 carbon atoms; or R?1 and R2¿ together with the carbon atom to which they are bound are a cyclic or bicyclic ring system with between 3 and 14 ring atoms. Said method comprises the production, as starting or intermediate products, of compounds of formula (II) in which R?3 and R4¿ are readily cleavable groups and R?1 and R2¿ have the meanings given above. Said compounds are cyclized under suitable reaction conditions to yield compounds of formula (I).
