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 alpha-substituted malononitriles can be used as substrate and the results suggest that pi-pi stacking interactions between the (hetero) aromatic rings of the catalyst and substrates are important in determining the degree of asymmetric induction.
