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.
许多天然聚醚毒素含有反式
吡喃梯形结构。我们描述了使用阳离子
金 (I) 催化环化合成聚醚反式
吡喃环系统。这种
金(I)催化的环化提供了高非对映选择性和高周转率。该方法有望应用于聚醚的合成。
