Synthesis of JKLM ring fragment of ciguatoxin via acetylene-cobalt strategy

A stereoselective synthesis of the JKLM ring fragment has been achieved through a coupling between two segments via heteroconjugate addition, seven-membered ether ring formation mediated by an acetylene cobalt complex and spiroketalization reaction.

Synthesis of the JKLM-ring fragment of ciguatoxin

A stereoselective synthesis of the LM-ring fragment has been achieved starting from a sugar derivative. A stereoselective synthesis of the JKLM-ring fragment has been achieved through a coupling between two segments via heteroconjugate addition, seven-membered ether ring formation mediated by an acetylene cobalt complex, and spiroketalization reaction.
