Abstract

Synthesis of 2 diastereoisomers of A/B fragments of ciguatoxin was achieved by connecting a hexose and 2 pentose derivatives with silylacetylene. The key steps are the cationic cyclization and reductive decomplexation of the acetylene biscobalthexacarbonyl complex.

Keywords

TWO DIASTEREOISOMERS WERE SYNTHESIZED FROM D-GLUCOSE AND D-ARABINOSE OR L-XYLOSE DERIVATIVES AS PARTIAL MODEL COMPOUNDS FOR THE A/B RING OF CIGUATOXIN.
