A Mannich-type three-component reaction involving aldehydes, acetamide, and enolizable ketones or β-keto esters for the preparation of β-acetamido carbonyl compounds in the presence of TMSCl is described. This newly developed protocol is operationally convenient, widely applicable, and highly diastereoselective.
