Spectral Characteristics of Cyclic Diarylheptanoids

Structural and spectral characteristics of the cyclic diarylheptanoids were reviewed.The UV,IR and NMR characteristics of cyclic diarylheptanoids were summarized,as well as the methods used to determine the absolute configuration of these compounds.It was shown that natural cyclic diarylheptanoids have different structural characteristics,particularly the H-6 of cyclic diphenyl ether diarylheptanoids.This work will provide a basic reference for studying the structure of the cyclic diarylheptanoids.
