6-Aminoindole (3) is obtained from the reaction of substituted 2,4-dinitrotoluene(1) condensation with N,N-dimethylformamide dimethyl acetal (DMFDMA) and reduction with Fe/HAc. Compounds 5(a^d) are synthesized from (3...6-Aminoindole (3) is obtained from the reaction of substituted 2,4-dinitrotoluene(1) condensation with N,N-dimethylformamide dimethyl acetal (DMFDMA) and reduction with Fe/HAc. Compounds 5(a^d) are synthesized from (3) reaction with POC13/DMF, PhCOCl/AgNO3 and thiourea respectively. The structures of 5(a^d) are analyzed and established by MS, IR and 1H NMR spectra. The antibacterial activities of the compounds have been tested against three kinds of bacteria. The results show that the compounds possess different bacteriactivities.展开更多
