α-蒎烯为原料,在质子酸催化下发生Wagner-Meerwein 重排得到α-萜品烯,再与马来酸酐发生Diels-Alder 环加成反应得到α-萜品烯马来酸酐3,然后与水合肼反应制备N-氨基-α-萜品烯马来酰亚胺4. 在冰醋酸催化下,4与各种取代苯甲醛反应,合成得到17 个新型α-萜品烯马来酰亚胺基酰腙化合物5a~5q. 初步探索了合成条件,并利用元素分析、1H NMR、13C NMR、LC-MS、FT- IR 等多种手段对目标产物作了分析表征. 初步的生物活性测试表明,大部分化合物具有一定的杀菌活性,其中化合物5n 在浓度为50 mg/L 时对苹果轮纹病菌、花生褐斑病菌和番茄早疫病菌的抑制率分别达91%、 83.3%和76.7%.

In this paper, α-pinene was converted into α-terpinene by Wagner-Meerwein rearrangement under catalysis of protonic acid, followed by Diels-Alder cycloaddtion reaction of α-terpinene with maleic anhydride to obtain α-terpinene-maleic anhydride adduct 3. Then, N-amino-α-terpinene -maleimide 4 was prepared by the reaction of compound 3 with hydrazine hydrate. Seventeen novel α-terpinene-maleimidebased acylhydrazones 5a~5q were synthesized by the reaction of compound 4 with substituted phenyl aldehydes under catalysis of glacial acetic acid. The synthetic conditions were investigated preliminarily. The target compounds were analyzed and characterized by means of elemental analysis, 1H NMR, 13C NMR, LC-MS, and FT-IR. The preliminary bioassay showed that most of the title compounds exhibited a certain fungicidal activity, in which compound 5n had inhibition rates of 91%, 83.3%, and 76.7% against Physalospora piricola, Cercospora rachidicola, and Alternaria solani, respectively, at the concentration of 50 mg/L.

Key words: α-pinene, N-amino-α-terpinene-maleimide, α-terpinene-maleimide-based acylhydrazone, synthesis, fungicidal activity
