The content of this article is mainly about the synthesis of a series of styrene chromones. Styrene chromone compounds have quite good potential in anti-cancer efficacy. Therefore, the use of synthetic methods can obtain styrene chromone compounds in a more efficient manner, and can Make different changes in the functional group, and study with Tzu Chi University and National Yangming Jiaotong University to develop other biological activities; the direction of synthesis in this article is the change of the functional group on the B ring of styrene chromone, one of which is a derivative 2 -(2-Pyridine) styrene chromone will also test the changes in fluorescence induced by its protonation degree, and explore whether it has potential in bioluminescent probes
