  Rhodium-Catalyzed Conversion of Furans to Highly Functionalized Pyrroles

  摘要：

  The synthesis of highly functionalized pyrroles has been achieved by reaction of rhodium-stabilized imino-carbenes with furans. The reaction features an initial [3+2] annulation to form bicyclic hemiaminals, followed by ring opening to generate trisubstituted pyrroles.

  A series of different furan-yn-ols were prepared by a three-step sequence. Their reaction with Gagosz's catalyst Ph3PAuNTf2 depends strongly on the substitution pattern of the Substrate and the quality of the leaving group. Benzofurans, alkylidenecyclopentenones or Meyer-Schuster type products can be obtained. Improving the leaving group quality leads to the preferred formation of benzofurans. (C) 2009 Elsevier Ltd.
