A simple and efficient protocol has been developed for the Michael addition ofamines to α,β-unsaturated esters under microwave irradiation. Under these conditions therewas a significant decrease in the reaction time, increases in the yields and increased purityof the products.

3-Aryl-6-methyl-2-thioxotetrahydropyrimidin-4(1H)-ones were proposed as a new class of anti-prostate cancer agents on the basis of molecular modeling studies. Stereoselectivesynthesis of 3-aryl-6-methyl-2-thioxotetrahydropyrimidin-4(1H)-one derivatives was achieved by chiral induction employing (R)/(S)-α-methyl benzylamine and subsequent debenzylation with HBr in AcOH afforded the desired enantiomers
