Guerrero-Corella, Andrea published the artcile2-Hydroxybenzophenone as a Chemical Auxiliary for the Activation of Ketiminoesters for Highly Enantioselective Addition to Nitroalkenes under Bifunctional Catalysis, Safety of (E)-4-(2-Nitrovinyl)benzonitrile, the publication is Angewandte Chemie, International Edition (2018), 57(19), 5350-5354, database is CAplus and MEDLINE.
An organocatalytic system is presented for the Michael addition of monoactivated glycine ketimine ylides with a bifunctional catalyst. The ketimine bears an ortho hydroxy group, which increases the acidity of the methylene hydrogen atoms and enhances the reactivity, thus allowing the synthesis of a large variety of α,γ-diamino acid derivatives with excellent stereoselectivity.
