... The target compounds were synthesized from diethyl adipate in 6 steps. Their structures were confirmed by IR, 1 H NMR spectra, X-ray and elemental analysis or HRMS. The preliminary bioassay results indicated that some compounds showed obvious inhibition effects against Brassica campestris, and the herbicidal activities were more than 60% at 100 μg/mL.
