Sml2or Sml3Mediated Aldol-Type Reaction of α-Halo Ketones with Aliphatic α-Diketones: Facile Synthesis of 2-Hydroxy-1, 4-diketones

A Novel Tandem Reaction of Chalcone with Malononitrile or Ethylcyanoacetate Promoted by Samarium (III) Iodide and Followed by Samarium (II) Iodide

Michael additions of active methylene compounds (for example: malononitrile, ethylcyanoacetate) to chalcones promoted by SmI3 gave 1,4-adducts which, after intramolecular coupling reactions induced by SmI2, furnished fine yields of cyclic products.

A C2-symmetric nickel diamine complex as an asymmetric catalyst for enecarbamate additions to butane-2,3-dione

Butane-2,3-dione was activated towards nucleophilic addition of enecarbamates by a series of metal triflate complexes of a C2-symmetric diamine to give stereogenic, aldol-like, t-alcohols, a novel nickel(II) triflate complex was identified as a good catalyst for this asymmetric transformation, and an aquo nickel(II) complex was identified by XRD techniques.
