Synthesis and physiological activity of ureas and amides with carvone residues.
The synthesis and herbicidal activity of ureas and amides with carvone residues were examined. (S)-(+)-(1) and (R)-(-)-Carvone(2) were converted to the respectively, primary amines(3) and (4) by oximation and reduction with LiAlH(4). Primary amine derivatives were further converted into the urea and amide compounds (3a) approximately (3e) and (4a) approximately (4e). The herbicidal activity of products (3a) approximately (3e) and (4a) approximately (4e) towards weeds found in a paddy field and field was measured in the pot. Products (3a) showed a particularly strong inhibitory effect on the growth of Amaranthus retroflexus(AR) and Setaria viridis(SV).
