T1  - C2-symmetric bisamidines : chiral Brønsted bases catalysing the Diels-Alder reaction of anthrones
T2  - Beilstein journal of organic chemistry
N2  - C2-symmetric bisamidines 8 have been tested as chiral Brønsted bases in the Diels- Alder reaction of anthrones and N-substituted maleimides. High yields of cycloadducts and significant asymmetric inductions up to 76% ee are accessible. The proposed mechanism involves proton transfer between anthrone and bisamidine, association of the resulting ions and finally a cycloaddition step stereoselectively controlled by the chiral ion pair.
