l-Proline-catalysed three-component domino reactions of ethyl 2-[(2-oxo-2-arylethyl)sulfanyl]acetate, aromatic aldehydes and ammonia provide a rapid and facile access to novel trans-6-aroyl-5-aryl-3-thiomorpholinones. This diastereoselective reaction presumably proceeds via a domino sequence comprising enamine formation, Mannich reaction and intramolecular amidation individual steps and resulting in
