2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.COA of Formula: C9H10O4

4-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) is an important target for new bleaching herbicides discovery. To search for novel HPPD inhibitors, a series of 2-(aryloxyacetyl)cyclohexane-1,3-diones were rationally designed and synthesized by an efficient one-pot procedure using of N,N’-Carbonyldiimidazole (CDI), triethylamine, and acetone cyanohydrin in CH2Cl2. A total of 58 triketone compounds were prepared in good to excellent yields. Some of the synthesized compounds displayed potent Arabidopsis thaliana HPPD (AtHPPD) inhibitory activity. 2-(2-((1-Bromonaphthalen-2-yl)oxy)acetyl)-3-hydroxycyclohex-2-en-1-one (I) displayed high, broad-spectrum and post-emergent herbicidal activity at the rate of 37.5-150 g ai/ha, nearly as potent as mesotrione against some weeds. Furthermore, I showed good crop safety against maize and canola at the rate of 150 g ai/ha, indicating that I might have the potential as herbicide for the weed control in maize and canola fields. I is the first HPPD inhibitor showing good crop safety towards canola. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4COA of Formula: C9H10O4).
