Abstract
A large number of herbicides act by interfering with chlorophyll biosynthesis. The diphenyl ether (DPE) and cyclic imide classes of herbicides have been found to inhibit protoporphyrinogen IX oxidase (Protox) although their chemical structures are completely different from each other; therefore, both types of herbicides could be classified as Protox inhibitors. It is noteworthy that most recent cyclic imides consisting of a highly functionalized phenyl group and nitrogen-containing heterocycle moiety exhibit superior efficacy against weeds at low rate of application of less than 10g/ha and some representatives also have good selectivity for crops. A few 5-membered cyclic imides have been already developed as practical herbicides and some of them are under development. Additionally, as an extension of 5-membered heterocycle chemistry, 6-membered cyclic imides such as pyrimidine and triazine hetero-cycles have been actively investigated during the last decade. Particularly, 6-trifluoromethyluracils have been reported to show much more potent activity than that of 5-membered cyclic imides.
