摘要 以2,6-二氯喹喔啉为起始原料、经Baylis-Hillman反应设计并合成了4个结构新颖的(6-氯喹喔啉-2-基氧基)苯基丙烯酸酯和丙烯腈衍生物,其结构经红外、核磁、元素分析确认。生物活性测定结果表明2-((3-(6-氯喹喔啉-2-基氧)苯基)(羟基)甲基)丙烯酸甲酯(3a)和2-((4-(6-氯喹喔啉-2-基氧)苯基)(羟基)甲基)丙烯腈(3d)具有有效的杀菌活性,在400ga.i./hm2的剂量下对黄瓜霜霉病的防效分别为100%和75%。 Four novel (6-chloroquinoxalin-2-yloxy)phenyl acrylate and acrylonitrile derivatives were designed and synthesized utilizing 2,6-dichloroquinoxaline as a starting material via Baylis-Hillman reaction. Their structures were confirmed by IR, ^1H NMR and elemental analyses. Evaluation of their biological activities showed that methyl 2-((3- (6-chloroquinoxalin-2-yloxy)phenyl)(hydroxy)methyl) acrylate (3a) and 2-((4-(6-chloroquinoxalin-2-yloxy)phenyl) (hydroxy)methyl) acrylonitrile (3d) exhibited efficient fungicidal activity, with 100% and 75% control of cucumber downy mildew (CDM) respectively at 400 g a.i./ha.
