SnCl2·2H2O-catalyzed efficient synthesis of β-acetamido ketones and β-acetamido ketoesters under solvent-free conditions

SnCl2·H2O has been found to be useful and highly efficient for the preparation of β-acetamido ketones and β-acetamido ketoesters by a one-pot reaction of aryl aldehydes, enolisable ketones, acetyl chloride and acetonitrile in a solvent-free media at room temperature. The present methodology offers several advantages such as excellent yields, simple procedure, short reaction times (1–2.5 h) and milder conditions.

A simpler protocol has been developed for the preparation of β-acetamido ketones and β-acetamido ketoesters by a one-pot reaction using SnCl2·2H2O as a catalyst in a solvent-free media at room temperature. The present methodology offers several advantages such as excellent yields, simple procedure, short reaction times (1–2.5 h) and milder conditions. Figure optionsDownload as PowerPoint slide
