A diamine-catalyzed asymmetric tandem reactionbetweenalpha,beta-unsaturatedketones and rhodanine derivatives has been developed to synthesize various spirocyclic compounds with high stereoselectivities (up to 99% ee and >20:1 dr). The products obtained contain two pharmaceutically relevant features: the biologically active rhodanine moiety embedded in a spirocyclic unit.
