Synthesis and Herbicidal Activity of N-(4-Ailyloxy-3-methoxy-benzyl)-N-alkyl Sulfonamides
[Aims] The paper aims to find new compounds with highly bioactivity.[Methods] 21 Novel compounds of N-(4-allyloxy-3-methyoxy-benzyl)-N-alkyl sulfonamides were designed and synthesized from the starting material of vanillic aldehyde.All the compounds were bioassayed against insect,fungi and herb.[Results] The structures of all compounds were confirmed by'H NMR.The preliminary assays showed that some compounds exhibited significant herbicidal activity.The inhibition rate of C9,C10,C11,C15,C16,C17,C19 and C21 to the Ambrosia tricolor reached 100％ at the concentration of 250 mg/L.[Conclusions] It's worthy to further study this kind of compounds.
