Description

technical field [0001] The invention belongs to the technical field of organic compounds and synthesis, and relates to iodine-catalyzed furanone derivatives and a synthesis method thereof. Background technique [0002] Furanones are an important class of organic compounds, which widely exist in many natural and non-natural products, most of which have strong biological activity. It can be used as an intermediate in organic synthesis and has great value in drug synthesis. Because of these advantages of furanone, people are very enthusiastic about the synthetic research of furanone compound, so the method for synthesizing furanone is also more, for example multi-component reaction and enynoic acid compound can synthesize furanone such as: document (1 ) Xiao-Feng Wu, Haijun Jiao, Helfried Neumann, and Matthias Beller, Chem.
