英文摘要： Some new alkyl coumarins, exhibited satisfactory antibacterial activities, will be taken as leading compound to search for novel agrochemical molecules. Based on the structural character of alkyl coumarins and the latest research result of coumarins for drug design all the world , a series of coumarin derivatives are being designed and synthesized. The idea above of structure modification will be carried out according to bioisosterism. All these derivatives are being synthesized and their structures are being comfirmed by IR, MS,NMR and so on. The bioassay research of these new compounds are being carried out during the same time. The relationships between the structure of these new derivatives and their bioactivities will be investigated acoording to the Hansch equation. And then, we intend to building up structure-bioactivities models and developing the typical QSAR studying in order to search for novel agrochemical molecules.
