Syntheses and herbicidal activity of pyrazolyl benzoxazole derivatives

(Chemical Equation Presented) In recent years, protoporphyrinogen oxidase (Protox) inhibitor herbicides are developed rapidly, because of this type of herbicides shows high herbicidal activity and low toxicity. In this paper, we prepared a series of new substituted pyrazolyl benzoxazole derivative, which were synthesized from 4-fluorophenol, via a serial of reactions included chlorination, acylation, condensation, ring closure, methylation, nitration, and so on. All the structures are confirmed by 1H NMR, MS and element analysis. Preliminary bioassay shows that most substituted pyrazolyl benzoxazole derivatives exhibit high herbicidal activity to the tested gramineous weeds and latifoliate weeds.

Herbicidal benzoxazinone- and benzothiazinone-substituted pyrazoles

The invention herein relates to titled compounds having the structure STR1 wherein the R1 -(R4)n members are as defined in the claims. Characteristic features of these compounds are the haloalkyl R2 radical and cyclization of two R4 members at the meta and para positions of the phenyl ring to form a substituted benzoxazinone ring fused to the phenyl or benzthiazinone ring. Such compounds are useful as active ingredients in herbicidal compositions to control undesirable weeds in various crops.
