  名称：

  A novel entry to 4,7-indoloquinones via the Fremy's salt oxidative degradation of 4-formyl-7-hydroxyindoles

  摘要：

  A novel synthetic approach toward 4-formyl-7-hydroxyindoles and 4,7-indoloquinones is described. Basically, two major operations need to be carried out, namely: (1) ozonization of the appropriately protected 4-amino-5-hydroxyindenes leading eventually to 4-formyl-7-hydroxyindoles and (2) Fremy's salt promoted oxidative degradation of the later compounds to the desired 4,7-indoloquinones. A formal synthesis of PDE I and PDE II has been achieved.
