Objective： The purpose is to synthesize 7-（3-Aryl） acryloxy-4-methyl Coumarins. Methods, Compounds were obtained from the reaction of 7-Hydroxy-4-methyl Coumarins with substituted cinnamic acid. Results. A series of 7-（3-Aryl） acryloxy-4-methyl Coumarins were synthesized. Their structures were unreported and unidentified by IR, UV and elemental analysis data. Conclusion- The method of synthesizing 7-（3-Aryl） acryloxy-4-methyl Coumarins is simple, convenient and feasible.
