Abstract
3-Methyl-2-thiono-4-thiazolidinone and aromatic aldehydes adsorbed on potassium fluoride on alumina gave under microwave irradiation 5-aryli dene-3-methyl-2-thiono-4-thiazolidinones in 70% to 90% yield. These co mpounds can be cleaved with sodium hydroxide on alumina into alpha-thi olacrylic acids in quasi-quantitative yields. Michael addition of diet hyl phosphite to 5-arylidene-3-methyl-2-thiono-4-thiazolidinone is des cribed for the first time.
