  Novel ether-ring transformation via a phenonium ion

  摘要：

  Upon treatment with CF3COOH at 70degreesC, trisubstituted-tetrahydropyrans. which were stereoselectively prepared from delta-lactones, were found to be converted into the corresponding 2,5-disubstituted-tetrahydrofurans stereospecifically via a phenonium ion. Furthermore, the stereocontrolled formal synthesis of paramycin 607 was achieved based on the ether-ring transformation. (C) 2002 Elsevier Science Ltd. All rights reserved.
