In order to find novel high active herbicidal lead compound, a series of N-cyclohexyl 2-{N-(3-trifluoromethyl-phenyl)-[3-(trifluoromethyl)benzoyl, 2-(substitutedphenoxy)propionyl, 2-(4,6-dimethoxypyrimidinyl-2-oxy)benzoyl]-amino}-substitutedphenylacetamides 3a3i were designed and synthesized by introducing 3-trifluoromethylbenzoyl, 2-aryloxy-pro-pionyl or 2-(4,6-dimethoxypyrimidin-2-yloxy)benzoyl and 3-trifluoromethyl phenyl moieties into the molecular skeleton via the Ugi reaction. Their structures were characterized by IR, 1H NMR, EI-MS, and elemental analyses. The preliminary bioassay (in vitro) indicated that some of compounds 3 displayed moderate to good herbicidal activity against Brassica campestris L at the concentration of 100 mg/L. The glasshouse bioassay (in vivo) showed that some of compounds 3 exhibited good herbicidal activities against B. campestris, A. retroflexus, E. crusgalli and D. sanguinalis in pre-emergence treatment at a dose of 1500 g/ha.

Key words: Ugi reaction, pyrimidinyl salicylic acid, aryloxy propanoic acid, phytoene desaturase (PDS) inhibitor, herbicidal activity
