Abstract

Many natural polyether toxins contain the trans-pyran ladder structure. We describe a synthesis of the polyether trans-pyran ring system by using cationic gold(I)-catalyzed cyclization. This gold(I)-catalyzed cyclization provided high diastereoselectivity and high turnover. This method is expected to be applicable to the synthesis of polyethers.
