• Triazolopyrimidines as a New Herbicidal Lead for Combating Weed Resistance Associated with Acetohydroxyacid Synthase Mutation

  Acetohydroxyacid synthase (AHAS; also known as acetolactate synthase; EC 2.2.1.6, formerly EC 4.1.3.18) is the first common enzyme in the biosynthetic pathway leading to the branched-chain amino acids in plants and a wide range of microorganisms. Weed resistance to AHAS-inhibiting herbicides, increasing at an exponential rate, is becoming a global problem and leading to an urgent demand of developing novel compounds against both resistant and wild AHAS. In the present work, a series of novel 2-aroxyl-1,2,4-triazolopyrimidine derivatives (a total of 55) were designed and synthesized with the aim to discover an antiresistant lead compound. Fortunately, the screening results indicated that many of the newly synthesized compounds showed a better, even excellent, inhibition effect against both the wild-type Arabidopsis thaliana AHAS and P197L mutants. Among them, compounds 5-3 to 5-17, compounds 5-19 to 5-26, compounds 5-28 to 5-45, and compound 5-48 have the lower values of resistance factor (RF) and display a potential power to overcome resistance associated with the P197L mutation in the enzyme levels. Further greenhouse in vivo assay showed that compounds 5-15 and 5-20 displayed "moderate" to "good" herbicidal activity against both the wild type-and the resistant (P197L mutation) Descurainia sophia, even at a rate as low as 0.9375 (g of ai/ha). The above results indicated that these two compounds could be used as new leads for the future development of antiresistance herbicides.

  A new strategy for the synthesis of 3,5-disubstituted phenols is established through one-pot Robinson annulation of α,β-unsaturated ketones with α-fluoro-β-ketoesters followed by in situ dehydrofluorination and tautomerization. This method has been extended to the synthesis of polysubstituted phenols and applied in the preparation of biologically active compounds.
