  Synthetic studies on the dienophile unit of methyl isosartortuoate. Part 2: SmI2-mediated 14-membered carbocyclization

  摘要：

  The dienophile unit of methyl isosartortuoate has been synthesized. The 14-membered carbocycle was constructed by a SmI2-mediated intramolecular Reformatsky reaction. The introduction of the oxo group at the gamma-position of the alpha,beta-unsaturated ester was achieved by rearrangement of an beta,gamma-epoxy ester. (C) 2002 Elsevier Science Ltd.
