Abstract

A simple and efficient catalytic method has been designed for the synthesis of a series of novel β-aminoketones using 3-aryl-4-formylsydnone, primary aromatic amine and cyclohexanone in the presence of ceric ammonium nitrate (CAN). The percentages of syn and anti isomers formed were elucidated using ¹H NMR spectral studies. The anti isomer was the major product.

Keywords: Ceric ammonium nitrate, syn/anti conformation, Sydnone, β-Aminoketone.
