In the course of the synthetic studies on gymnodimine, a potent shellfish toxin, the asymmetric construction of the azaspirocyclic part was achieved by the (-)-siam·Cu(SbF6)2 complex catalyzed intermolecular Diels-Alder reaction in high exo- and enantioselectivities.
在对 Gymnodimine 这种强效贝类毒素的综合研究过程中,通过(-)-siam·Cu(SbF6)2 配合物催化的具有高外向选择性和对映选择性的分子间 Diels-Alder 反应,成功实现了氮杂螺环部分的不对称构建。
