A novel three-component expeditious synthesis of 3,6-diaryl-5-mercaptoperhydro-2-thioxo-1, 3-thiazin-5-ones from 2-methyl-2phenyl- 1,3-oxathiolan-5-one, an aromatic aldehyde and an N-aryldithiocarbamic acid is reported. The synthesis is diastereoselective and involves tandem Knoevenagel, Michael and ring transformation reactions under solvent-free microwave irradiation in a one-pot procedure. (c) 2005 Elsevier Ltd.
