Abstract
Multicomponent reactions (MCRs) are emerged as one of the most imperative synthesis route in organic synthesis due to their wide application range in pharmaceutical chemistry. A variety of β-acetamido ketones were readily prepared in good to excellent yield (90.-95%) via four component reaction of aromatic aldehydes, enolizable ketones, acetonitrile, acetyl chloride in presence of mix metal oxide CuO-SnO₂ as versatile catalyst. The corresponding compounds were obtained in good to excellent yield, under mild conditions and ambient temperature.
