    Jul 28, 2005 · The first direct enantioselective organocatalytic intramolecular Diels−Alder reaction has been accomplished. The use of iminium catalysis has provided a new catalytic strategy for the enantioselective [4 + 2] cycloisomerization of a wide variety of tethered diene-enal systems. The use of imidazolidinones 1 and 2 as the asymmetric catalysts has been found to mediate the enantioselective ...Cited by: 247

    Diels or no Diels? A bifunctional organic catalyst based on the thiourea motif is able to coordinate both diene and dienophile in an unprecedented asymmetric Diels–Alder reaction of 3‐vinylindole derivatives, giving a rapid access to optically active tetra‐ and hexahydrocarbazoles with excellent results in terms of yields, diastereoselectivities, and enantioselectivities.

    A practical and environmentally friendly organocatalytic process for the synthesis of optically active highly substituted spiro[5,5]undecane‐1,5,9‐triones was achieved through the reaction of an aldehyde, an enone, and Meldrum's acid in the presence of a catalytic amount of chiral amino acid (see scheme). The Diels–Alder products were obtained as single diastereomers in excellent yields ...
