Abstract
Three-component reactions for the synthesis of substituted dihydropyrimidin es (4), chromenes (8) and tetrahydroquinolines (11) have been performed in water and in the presence of a montmorillonite KSF clay. The products, easi ly isolated from the reaction mixture by crystallisation, are obtained in h igh yield and selectivity and the catalyst can be recycled for many runs wi thout losing its activity.
