A stereoselective method for the synthesis of substituted tetrahydropyran derivatives employing a tandem SN2−Michael addition sequence to vinylogous carbonates is developed. The method is extended to the synthesis of bicyclic ether motifs present in polyether ladder toxins.
开发了一种立体选择性的合成取代四氢吡喃衍生物的方法,该方法利用串联的S N 2-Michael加成序列到乙烯基碳酸酯。该方法扩展到聚醚梯形毒素中存在的双环醚基序的合成。
