    Abstract: The invention concerns substituted lactic-acid derivatives, containing an organic nitrogen group in the beta position, of general formula (I) in which the substituents R2 to R5 and X are as defined in the description and N is one of the following groups: a) an -N¿3?, -NC, -NCS or -NCO group; b) a group (1) in which R?14 and R15¿ are hydrogen, an aliphatic, cycloaliphatic or aromatic organic C-group with up to 20 carbon atoms or together form an optionally substituted C¿4?-C7 alkylene chain closed to give a ring in which one methylene group may be replaced by oxygen, sulphur or nitrogen; c) a group (2) in which the groups are defined as follows: R?16¿ hydrogen, alkyl, haloalkyl, alkenyl, alkinyl, cycloalkyl or optionally substituted phenyl, B a group (3), -OR?19 or -NR14R15, R14 and R15¿ being as defined above and R?17 and R19¿ being defined as follows: R17 hydrogen, alkyl, haloalkyl, alkenyl, alkinyl, cycloalkyl or optionally substituted phenyl, an OR18 group in which R18 is: hydrogen, alkyl, haloalkyl, alkenyl, alkinyl, cycloalkyl, phenyl or substituted phenyl, a group (4) in which R?14 and R15¿ are as defined above; R19 hydrogen, alkyl, haloalkyl, alkenyl, alkinyl, cycloalkyl, phenyl or substituted phenyl; d) a group (5) in which R?20 and R21¿, which may be the same or different, are hydrogen, alkyl, alkenyl, alkinyl, cycloalkyl or phenyl, whereby the organic groups may be substituted, or R?20 and R21¿ together form an optionally substituted C¿4?-C7 alkylene chain closed to give a ring or together form an optionally substituted C3-C6 alkylene chain closed to give a ring including a hetero-atom selected from the group comprising oxygen, sulphur and nitrogen; R is a formyl group, COOH or a group which can be hydrolysed to COOH and Y is sulphur, oxygen or a single bond. Compounds of formula (I) have herbicidal and pl ant-growth-regulating properties. In addition, they exhibit an antagonistic action with respect to herbicides of the cyclohexenone type.
