oxylic acid-4-hydrogen sulphate (supported on silica gel), a green and non-toxic catalyst, is described for the preparation of β-acetamido ketones in good to excellent yields. An efficient multi-component procedure, catalysed by L-pyrrolidine-2-carboxylic acid-4-hydrogen sulphate (supported on silica gel), as green and non-toxic catalyst, has been applied for the preparation of \u03b2-acetamido ketones
