A carbene-catalyzed addition reaction between isothioureas and enals under oxidative conditions is reported. The key steps of our reactions involve the formation of two carbon–nitrogen bonds in a highly regio-selective manner. A variety of sulphur-containing 5,6-dihydropyrimidin-4-ones are obtained with high optical purity.
