7-Methyl(ethyl)indoline-2,3-diones 1a,1b as the raw materals were first alkylated to give the corresponding N-alkyl-7-methyl(ethyl indoline-2,3-diones(2a1-2a5,2b1-2b5). Compounds 1a,1b,2a1-2a5 and 2b1-2b5 were then underwent the condensa-tion reaction with 1,2-diaminobenzene in the presence of acetic acid or water as solvent and tetrabutyl ammonium bromide(TBAB) as phase transfer catalyst to afford a series of new 6H-indolo[2,3-b]quinoxaline derivatives 3a-3b,3a1-3a5,3b1-3b5 with good yields of 70. 0%-85. 8%. Their structures were confirmed by IR,MS,1 H and 13 C NMR spectra. Fluorescence spectroscopy showed that compounds 3a-3b,3a1-3a5 ,3b1-3b5 had good fluorescence properties.
