  Synthesis of the Fully Functionalized ABCDE Ring Moiety of Ciguatoxin

  摘要：

  A fully functionalized ABCDE ring moiety of ciguatoxin (CTX), the major causative agent of ciguatera poisoning, was synthesized for the first time. The present strategy involves the efficient installation of the C5-dihydroxybutenyl substituent and construction of the tetrahydrooxepin E ring using a novel alpha-chlorosulfide synthon.

• Stereocontrolled synthesis of the ABCDE ring moiety of ciguatoxin CTX3C

  The ABCDE ring moiety of ciguatoxin CTX3C, a major causative agent of ciguatera poisoning, was stereoselectively synthesized. The key transformations are a chiral auxiliary-based asymmetric alkylation and an asymmetric aldol condensation, which controlled the formation of the C11 and C21-stereocenters, respectively. A highly practical and efficient route to the ABCD ring fragment, a common precursor for the divergent synthesis of the left wings of ciguatoxins, was also established. (C) 2004 Elsevier Ltd.

• Synthesis of trans-fused tetrahydrooxepins: stereoselective allylation of sulfur or fluoro-substituted tetrahydrooxepins

  日期：2008.2

  An efficient route to the trans-fused tetrahydrooxepin corresponding to the E ring of ciguatoxin was developed. Wide screening of allylation reactions of sulfur or fluoro-substituted tetrahydrooxepin revealed that the optimum method for obtaining the beta-allylation product selectively was the use of a combination of allyltrimethylsilane and TiCl4 with 6-fluoro-7-hydroxytetrahydrooxepin.
