| titleOfInvention | Method for producing 1-substituted 5-hydroxypyrazoles |
| 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 R<1> is hydrogen, an aliphatic group with between 1 and 8 carbon atoms, C1-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 R<2> 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 R<4> are readily cleavable groups and R<1> and R<2> have the meanings given above. Said compounds are cyclized under suitable reaction conditions to yield compounds of formula (I). |
