以香豆素-3-甲酸与亚硫酰氯的反应产物香豆素-3-甲酰氯,与硫氰酸钾反应,再与各种杂环胺反应合成了N-(香豆素-3-甲酰基)-N’-取代硫脲类衍生物.其结构由IR,1H NMR,质谱和元素分析所表征,并初步研究了目标化合物抗菌活性和植物生长促进作用,发现它们大多数有优良的抑菌活性和较明显的植物生长促进活性。 Coumarin-3-formyl chloride, a reaction product of coumarin-3-carboxylic acid and thionyl chloride, was reacted with potassium thiocyanate and then reacted with various heterocyclic amines to synthesize N- (coumarin-3- Formyl) -N’-substituted thiourea derivatives. Their structures were characterized by IR, 1H NMR, mass spectrum and elemental analysis. The antibacterial activity of the target compounds and the promotion of plant growth were studied. Most of them were found to have excellent Antibacterial activity and more obvious plant growth promoting activity.
