A dual-metal-catalyzed asymmetric [3+2] annulation of 2-vinyloxiranes with the challenging nucleophilic dipoles (imino esters) was achieved. It was successfully applied to the stereodivergent synthesis of structurally rigid spirocyclic framework. A series of spiro compounds bearing a pyrroline and an olefin were synthesized in an enantio- and diastereodivergent manner.

通过双金属催化 [3+2] 环化 2-乙烯基环氧乙烷与亲核偶极子的对映和非对映发散合成螺环
实现了具有挑战性的亲核偶极子(亚氨基酯)的 2-乙烯基环氧乙烷的双金属催化不对称 [3+2] 环化。它成功地应用于结构刚性螺环骨架的立体发散合成。以对映和非对映发散方式合成了一系列带有吡咯啉和烯烃的螺环化合物。
