摘要
Access to a medium-sized unit of 15-seco-eleutheside analog 19 has been opened through the NiCl2/CrCl2-mediated intramolecular condensation of iodoaldehyde 8 with excellent yields. Transformation of the phenylcyclononanol 15 into the tetracyclic analog 19 was achieved in a four-step sequence with 65%, overall yield. (C) 2002 Elsevier Science Ltd. All rights reserved.
