C(2)-symmetric bisamidines: Chiral Brønsted bases catalysing the Diels-Alder reaction of anthrones
C(2)-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 anthron...
