  Enantioselective fluoride ring opening of aziridines enabled by cooperative Lewis acid catalysis

  摘要：

  The enantioselective ring opening of aziridines using a latent source of HF is described. A combination of two Lewis acids, (salen)Co and an achiral Ti(IV) cocatalyst, provided optimal reactivity and enantioselectivity for the trans beta-fluoroamine product. The use of a chelating aziridine protecting group was crucial. Acyclic and cyclic meso N-picolinamide aziridines underwent fluoride ring opening in up to 84% ee, and the kinetic resolution of a piperidine-derived aziridine was performed with k(rel)=6.6. The picolinamide group may be readily removed without epimerization of the fluoroamine. Preliminary studies revealed a bimetallic mechanism wherein the chiral (salen)Co catalyst delivers the nucleophile and the Ti(IV) cocatalyst activates the aziridine. (C) 2013 Elsevier Ltd.

• Chiral magnesium(ii)-catalyzed asymmetric ring-opening of meso-aziridines with primary alcohols

  日期：——

  The asymmetric ring-opening of meso-aziridines with primary alcohols is realized using an N,N′-dioxide–Mg(OTf)2 complex as the catalyst. The desired vicinal trans-β-amino ethers are afforded in good yields and enantioselectivities. Aniline and water could also be used as the nucleophiles for the ring-opening in an identical catalyst system.

  以N,N′-二氧化物–Mg(OTf)2复合物作为催化剂，初级醇对meso-氮杂环丁烷的不对称开环反应得以实现。所需的邻位反式-β-氨基醚以良好的产率和不对称选择性获得。苯胺和水也可以作为在相同催化体系中的核亲电试剂用于开环反应。
