    Abstract

    Comparison of the relative reactivities of the benchmark catalysts for iminium ion catalysed Diels-Alder cycloaddition under optimised literature conditions showed the imidazolidinone scaffold to possess significantly superior levels of activity in the Diels-Alder cycloaddition when compared to diarylprolinol silyl ethers.
