  Convergent synthesis of the ABCDE ring system of ciguatoxin CTX3C

  摘要：

  Ciguatoxin CTX3C is a representative congener of the ciguatoxins, which are known to be the principal causative-agents of ciguatera seafood poisoning. The structure of CTX3C spans over three nanometers and is characterized by thirteen ether rings. To attain a practical construction of this molecule, efficient supplies of the structural fragments are crucial. Herein we report the convergent synthesis of the ABCDE ring fragment featuring (i) alkylative coupling of the AB ring and E ring, and (ii) ring-closing olefin metathesis.

  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.
