[摘要]:We report the preparation of symmetrical bis(indolyl)acetamides using the dimerization of 2-hydroxy-(2-indolyl)acetamides and unsymmetrical bis(indolyl)acetamides via electrophilic substitution of indoles with 2-hydroxy-(2-indolyl)acetamides. Both conversions were mediated by protic acid in THF at room temperature. |
