摘　　要：在三乙胺催化下,利用取代水杨醛、氰乙酸酯和5-氨基吡唑的三组分反应合成了一系列5-氨基色烯并[4,3-d]吡唑并[3,4-b]吡啶-6(3H)-酮衍生物4a^4v.荧光研究表明部分合成得到的化合物具有高的荧光量子产率.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.
