  Solvent-Controlled Leaving-Group Selectivity in Aromatic Nucleophilic Substitution

  摘要：

  A solvent-controlled inversion of leaving group ability allows selective access to either of two internal substitution products in SNAr reactions of substrates with competing leaving groups. Application of this principle in a selective synthesis of the highly functionalized xanthone core of the antibiotic FD-594 is presented.
