    Project supported by the Major Basic Research Project of the Natural Science Foundation of the Jiangsu Higher Education Institutions (Nos.15KJA150006,17KJA150006).

A series of 5-aminochromeno[4,3-d]pyrazolo[3,4-b]pyridin-6(3H)-one derivatives 4a~4w were synthesized by three-component reactions of salicylaldehydes, ethyl cyanoacetate and 5-aminopyrazoles catalyzed by triethylamine (TEA). The properties of the synthesized compounds were examined by fluorescence spectroscopy and the results indicated that some compounds were possessed high fluorescence quantum yields.

Key words: chromeno[4,3-d]pyrazolo[3,4-b]pyridine, three-component synthesis, fluorescence property
