Studies on the constituents of Lespedeza homoloba Nakai. I. The structure of lespedeol A

A new isoflavanone derivative named lespedeol A was isolated from the bark of Lespedeza homoloba NAKAI. The structure was presumed to be 2', 4', 5, 7-tetrahydroxy-6-geranylisoflavanone by spectral and chemical data, and this presumption was confirmed by the synthesis of 2', 4', 7...

Summary:A new isoflavanone derivative named lespedeol A was isolated from the bark of Lespedeza homoloba NAKAI. The structure was presumed to be 2', 4', 5, 7-tetrahydroxy-6-geranylisoflavanone by spectral and chemical data, and this presumption was confirmed by the synthesis of 2', 4', 7-trimethoxy-5-hydroxy-6-tetrahydrogeranylisoflavone derived from lespedeol A.
