In this thesis, C-glycosides from monosaccharide have been investigated based on the review of C-glycosides compounds including application of heterocyclic quinoxaline, the synthetic methods of C-glycoside and the synthetic methods for quinoxalines. A series of quinoxalines C-glycosides have been synthesized using the new method. In consideration of the experimental results, we concluded the mechanism. In addition, the regioselective acylation in carbon glycoside was studied by dibutyltin oxide. The main re...
