As a new extention of monitored aminolysis of 3-acyl-1,3-thiazolidine-2-thione(ATT), a convenient procedure for the synthesis of αβ-unsaturated carboxylic acid amides has been developed using a new hetero-bifunctional reagent, 3-dimethylphosphonoacetyl-1,3-thiazolidine-2-thione (DMPATT).DMPATT was effectively used as the bridging reagent between amino (or imino) compounds and aldehydes (or ketone) to afford various olefinic amides in good yields.KEYWORDS - thiazolidine-2-thione; hetero-bifunctional reagent; αβ-unsaturated amide; Wittig reaction; ferulyltryptamine

3-Acylthiazolidine-2-thiones (1) were easily prepared and they were treated with several amines in dichloromethane to give amides 4 in very high yields within a short time.Aminoalcohols and aminophenols were selectively converted into acylaminoalcohols and acylaminophenols, respectively, by this reaction.One can monitor the reaction by disappearance of the yellow color of the starting material 1.Some amide alkaloids (15-18) have effectively been synthesized.
