More Information
Summary:This invention relates to a new method of synthesis common mignonette element. The initial material is phloroglucin, protective group is not needed, 3í»,4í»-dimethoxy-5,7-ferrichrysin can be got after it directly condensated and cyclizated with 3,4-dimethoxy benzoyl acetic acid ethyl ester, then common mignonette element is got after catalysis demethylate by alchlor/ pyridine, the whole yield is 34.2%.
