Melamine trisulfonic acid as a highly efficient and reusable catalyst for the synthesis of β-acetamido ketones

A highly efficient protocol for the one-pot multi-component condensation of acetophenones with aromatic aldehydes,acetonitrile and acetyl chloride in the presence of melamine trisulfonic acid (mtsa) as a highly efficient and recyclable sulfonic acid-containing catalyst at room temperature is described. in this method,β-acetamido ketone derivatives are obtained in high to excellent yields and in relatively short reaction times. © 2012 hindawi publishing corporation.
