A one-pot, three-component reaction between an aromatic aldehyde,
an enolizable ketone or a β-keto ester, and a nitrile in
the presence of acetyl chloride is accomplished efficiently using cyanuric
chloride in an aqueous medium to give the corresponding β-acetamido
ketone or ester in high yield.
β-acetamido ketone - multicomponent reaction - cyanuric chloride - aqueous medium
