Paragraph 0045; 0048, (2018/10/11)
The invention discloses a diacylhydrazines derivative containing an indole skeleton as well as a preparation method and application thereof. A structure of the diacylhydrazines derivative containing the indole skeleton disclosed by the invention is shown in a formula: the formula (1) is shown in the description, wherein R1 is selected from -H and -F; R2 is selected from -H and -Br; R3 is selectedfrom -H, -Cl and -I; R4 is selected from -CH3, -Cl, -H, -F and -CF3. A synthetic method of the diacylhydrazines derivative has the advantages of simple process, less steps, lower cost, high efficiencyand convenience and has good universality, and moreover, the diacylhydrazines derivative can be produced in batch.
