One-Pot Synthesis of β-Acetamido Ketones Using Boric Acid at Room Temperature

Abstract EN

β-acetamido ketones were synthesized in excellent yields through one-pot condensation reaction of aldehydes, acetophenones, acetyl chloride, and acetonitrile in the presence of boric acid as a solid heterogeneous catalyst at room temperature.

It is the first successful report of boric acid that has been used as solid acid catalyst for the preparation of β-acetamido ketones.

The remarkable advantages offered by this method are green catalyst, mild reaction conditions, simple procedure, short reaction times, and good-to-excellent yields of products.
