Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is an important herbicide target. In this study, a series of novel diphenyl ethers derivatives with 2-pyrrolidone structure were developed as PPO inhibitors. Thereinto, compound H7 (IC50 = 0.0262 mg/L) has better PPO enzyme inhibitory activity than commercial herbicide oxyfluorfen (IC50 = 0.0426 mg/L). Greenhouse herbicidal activity experiments exhibited that even under the condition of 37.5 g ai/ha, H7 still had excellent broad-spectrum herbicidal activity. Moreover, rice, peanut, and cotton had strong tolerance to H7 at 300 g ai/ha. Field trial showed that H7 had comparable herbicidal activity to oxyfluorfen. These experimental results indicated that H7 could be developed as a novel PPO Inhibitor candidate for weed control in the field.

Successive treatment of arenes with acyl chlorides and AlCl3, the addition of water and removal of solvent, the reaction with NH2OH?HCl and K2CO3, and the reaction with diphenylphosphoryl azide and DBU under warming conditions gave the corresponding 5-alkyl-1-aryltetrazoles efficiently in good to moderate yields. The present method is one-pot transformation of arenes into 5-alkyl-1-aryltetrazoles using the Friedel-Crafts acylation and the Beckmann rearrangement under transition-metal-free conditions.
