C2-symmetric bisamidines: Chiral Brønsted bases catalysing the Diels-Alder reaction of anthrones
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...
