    Abstract: Derivatives of 3-hydroxycarboxylic acids of the formula I in which the substituents have the following meaning: R is a CHO group, a CO2H group or a radical which can be hydrolysed to give CO2H, R is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy or alkylthio; X is nitrogen or CR , R being hydrogen or together with R forming a 3- to 4-membered alkylene or alkenylene chain in which one methylene group in each case is replaced by oxygen; R is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy or alkylthio, or R is linked with R as indicated above to give a 5- or 6-membered ring; R is an optionally substituted alkyl, alkenyl or alkynyl group; a cycloalkyl or cycloalkenyl group which can contain an oxygen or sulphur atom and is optionally substituted; optionally substituted phenyl or naphthyl or an optionally substituted heteroaromatic; or R and R , together with the adjacent carbon atom, form a 3- to 8-membered ring which can contain an oxygen or sulphur atom and can carry 1 to 3 radicals; R is hydrogen, alkyl, alkenyl, alkynyl, alkylcarbonyl, alkoxycarbonyl, haloalkyl, cycloalkyl, alkoxyalkyl, alkylthioalkyl or optionally substituted phenyl, or R is linked with R as indicated above to give a ring; Y is sulphur, oxygen or a single bond; R is the radicals mentioned for R and additionally an amino group -NR R or a radical ...
