  4-Chromenesulphones: synthesis and transformation to isoflavonoid models

  摘要：

  Novel sulphones derived from chromenes through Substitution at C-4 were prepared. It has been shown that, after conjugate addition of phenyl lithium and sulphone function manipulation on the adducts, these molecules lead to isoflavan, isoflavene and isoflavanone models.
