In order to further study the structure-activity relationships (SAR) of the title compounds and find new kinds of herbicides, nineteen new compounds were prepared by reaction of nineteen ketoacid esters with amio-acid esters. All of them have been confirmed by 1H NMR and elemental analysis. The preliminary bioassay results indicated that their inhibiting rates were higher than sulcotrione. In comparison with the re-ported compounds with excellent herbicidal activity, their inhibiting rates against B. campestrisroot were elevated significantely while their inhibiting rates against E. crus-galli were not improved.

Key words: pyrrolidine, p-hydroxyphenypyruvate dioxydenase, herbicide
