摘要 以吲哚甲醛和硝基乙烷为起始原料,经Henry、Pictet-Spengler等反应合成了12个9-取代-3-甲基-β-咔啉衍生物,其中10个未见文献报道,其结构均通过核磁共振和质谱确证。毒力测定结果表明:化合物Z-5(3-甲基-9-异丙基-β-咔啉)抑制玉米弯孢霉叶斑病菌Curvularia lunata和番茄灰霉病菌Botrytis cinerea孢子萌发的EC50值分别为4.23和6.73μg/mL;相应地,Z-7(3-甲基-9-炔丙基-β-咔啉)的EC50值分别为11.16和7.51μg/mL。 The β-carboline derivatives were synthesized from indole formaldehyde and nitroethane via the Henry and Pictet-Spengler reaction. Twelveβ-carboline derivatives were obtained and ten of them were new compounds. The structures of all the derivatives were confirmed by ^1H NMR, 13 C NMR and ESI-MS. Antifungal activity test showed that compound Z-5 (9-isopropyl-3-methyl-fl-carboline) has significant inhibitory activity against the spore germination of Curvularia lunata(Walker) Boedijn and Botrytis cinerea with ECs0 value of 4.23 and 6.73 μg/mL. Compound Z-7 (3-methyl-9-propargyl-β- carboline) showed similarly antifimgal activity as that of Z-5 with ECs0 value of 11.16 and 7.51 p,g/mL, respectively.
