摘　　要：以马来松香酸为原料,经酰氯化和与苯胺类化合物的N-酰化反应后,得到9个新颖的马来松香酸基酰胺类化合物,其结构均经1H NMR、13C NMR、IR和元素分析确证。初步的除草活性测试表明,在浓度为100μg/mL时,目标产物对油菜的胚根生长有一定抑制作用,其中化合物3c(R=4-ClC6H4)的活性最好,抑制率为66.1%。Maleated rosin acid chloride was prepared using maleated rosin acid as starting material,followed by the N-acylation reaction of the acyl chloride with phenyl amines to give nine novel maleated rosin acid-based amides. The structures of the target compounds were confirmed by IH NMR,13C NMR, IR and elemental analysis. The preliminary herbicidal activity assay showed that, at the concentration of 100 μg/mL, the target compounds exhibited a certain growth inhibition activity against rape root（Brassica campestris） , in which compound 3e （R = 4-C1C6H4 ） had the best inhibition rate of 66.1%.
