During the course of our synthetic studies on ciguatoxin, synthesis of H-I-J tricyclic fragment has been stereoselectively achieved starting from a d-glucal derivative. The key steps are Sonogashira coupling reaction and cobalt complex-mediated oxocane cyclization.

of ciguatoxin with high stereoselectivity has been achieved starting from a sugar derivative directed toward the synthesis of the right part of ciguatoxin. Sonogashira coupling of a vinyl iodide with an acetylenederivative, cobalt complex-mediated (seven- and eight-membered ring) cyclizations and a heteroconjugate additionreaction play important roles in the current research work.
