Abstract

Diethyl carbonate is shown to be a suitable, sustainable solvent in which to carry out quinine catalysed asymmetric Michael additions of malononitriles to enones. Both malonitrile and α-substituted malononitriles can be used as substrate and the results suggest that π-π stacking interactions between the (hetero)aromatic rings of the catalyst and substrates are important in determining the degree of asymmetric induction.
