A highly stereoselective construction of 2,6-cis-disubstituted tetrahydropyrans was achieved by using an intramolecular amide enolate alkylation with KHMDS. The efficiency and practicality of this methodology was successfully demonstrated in the total synthesis of (−)-centrolobine (1).
通过用KHMDS进行分子内酰胺烯酸酯烷基化,实现了2,6-顺式-二取代的四氢吡喃的高度立体选择性的构建。该方法的效率和实用性已在(-)-中心洛宾(1)的全合成中得到了成功证明。
